a photo is worth a thousand words.

(There is no concept of polarity, in the loop because the current changes direction 100 to 120 times a second (power frequency).

Ive been pretending to be okay and acting as normal as possible, but Im actually completely heartbroken after a recent breakup. Its painful and really affecting me, to the point where I cant concentrate at work, Ive lost my appetite, I cant sleep, and It feels as if my whole world has been turned upside down. I loved him so much. He said so many cruel things to me and it made me realize he must not have loved me the way I loved him, or he wouldnt have said such horrible things. How do I handle the heartbreak and why cant I accept that he didnt love me and just forget about him?

but I think this circuit , shows a few more pieces.

But during the surge, the fuse will not blow if it is a longer duration and lower value )10 to 50%).

He then asserts :

Hi everybody! I have been looking at posts on narcs and narc abuse on here and if has really helped me out a lot. I am currently struggling with my situation and need some advice/support. I met a narc last year, everything seemed to good to be true. Love bombing, always texting calling and taking me on dates. Everything changed when someone warned me about him out in public in front of him and who he is. This caused a conflict with us and the love bombing seized. he would tell me that everything is okay and i can come and talk. He would set a time limit on me and kick me out after that. he would then text me like everything was fine and we hung out again and after that he completely ghosted me for one week. He came back and texted me a week later laughing about the ghosting and acting like nothing had happened. he continued to text me ( not like in the beginning) make plans with me, then on the day of the plans he would just ghost me. One day he would act interested the next silence. i contacted him a month later and he acted like nothing happened. He was on a vacation and sent me a picture of another woman ( someone he allegedly met on the trip) to strike a reaction but i never gave him one. After the trip he came to my place and was extremely rude, accusing me of going on dates with a bunch of men. The next day he accused me of being an alcoholic and that he wanted nothing to do with me but said well maybe we can be "friends" then ghosted me i assumed at this point it was over and i would never hear from him again. He contacted me on the holiday a month later acting like everything was great. We ended up hanging out a month or so later and when we hung out it went well, i thought things were going in the right direction. after we hung out.. silence. I would try to text him and if he replied it would be very short then he just stopped replying. He ghosted me for almost three months. I thought he was done this time and of course he popped up again like nothing happened. At this point i was getting sick of if so i questioned him as to why he dissapeared and always does this. Of course he had some sob story about a injury and family member dying of cancer. I felt pity for him and he gave me an apology.. so i took him back stupidly. things seemed to be going smooth for a couple months, of course until his family member died and his injury got better he never contacted me and was distant. Menawhile, i was there for him during the difficult time for him. He lied to me about the funeral and never wanted to chat. I was chasing him and he would always claim nothing was wrong but when i said i thought he used me when he was down he could not handle it and would always tell me he didnt care and to go away. I would get so upset i would try texting him to work it out he would barelt respond and if he did he would not be nice about it. we did hang out a couple times after that, he would ignore me after. One day i was like hey i think you are seeing someone else, and i was like well ixam seeing someone so no problem if you are he said " buy bye good luck with your new guy stop contacting me" i was devastated and tried to get into contact with him for weeks then i just gave up and accepted it was over. He ended up contacting me a month later acting like everything was fine. He wanted to go out and have drinks i told him i would. He and i both seemed to have a great time. He ends up ignoring me again. I kept texting him trying to figure out what was wrong. He kept saying everything was fine and i said ok can we hang out again? He said maybe i was like why? He just kept saying maybe … our last conversation we had… i said what is wrong ? He said nothing is wrong everything is fine. I asked him why he keeps saying maybe. He said " maybe but i dont want to see you right now" i said why? He saix " im just not feeling it, if i wanted to date i would" i said why did you contact me less then a week ago wanting to go out? He said i didnt.. even though he did. So i said should i just move on or what? He said whatever you want to do. So i said that he was really confusing me and asked him if he had anything more to say before i move on? My messages were turning green so i panicked he blocked me and reacted irrationally. I said " omg did you block me? My messages are not going through. Even texted him on my work phone asking what was up. And called him twice ( please dont judge me i know it is pathetic i never was this type of girl before him) so he replied and said " Ok I'll block you now" then immedietly blocked me. He has never blocked me before since I have met him he will just ghost. Is this ths final discard aka " grand finale? Did i just push him too far? this has upset me so much its hard to even function.

The third is lightning and “how it gets conducted into a home.”

He then describes the function of a fuse.

What is lightning?

Why do some people dislike Gilmore girls?

There is no harm in having the surge suppressor along with the fuse in the circuit. The fuse will not open up until the current melts the link. This will take time, and in the interim, that jolt will get transmitted into the power supplies.

so, what happens?

There are three different concepts here that are getting confused.

Do Republicans realize that the power of the people is invested in 'representative government'? If so, why did they elect a pathological liar?

This is a high voltage low current spike that comes down the line because of the power poles being struck, and the voltage suppressors activating on the primary side of the transformer.

so, the loop of wire then, when put together with another loop reduces the ‘noise’ on a power line.

“ A fuse is a device which protects the (circuit) against overload and short circuit.”

You hold the door open for a lady and she stops in her tracks and screams at you, ‘Don’t hold the door for me! I’ll get it myself!’ What are your feelings or immediate reaction?

the problem then depends on "how fast does the fuse operate?".

But it can get overloaded, and no longer works.

what exactly is a ‘surge’ protector?

This is an electronic circuit designed to clamp voltages so that the Voltage Potential that appears at the outlet is never going to exceed the nominal value.

OK, this is Mohan Rajaratnam’s definition of a Surge suppressor.

Upvotes:

but this device (an Inductor) … impedes the rapid changes in the current.

Is there such a thing as "left wing fascism"? If not, what is an example of a political ideology that is often mistakenly labeled as "left wing fascism"?

So combined with a device called a MOV or Metal-oxide-resistor, then forms the 3rd part of a “surge suppressor “.

What does a fuse do?

I post the exact comment here.

The bolt then partially travels down the line to your home.

Lightning arrestor is a spark-gap device, and can be installed anywhere. What is important, is that the wire is thick enough to withstand the lightning bolt and conduct the energy away from the building.

“ … to protect building, lightning arrestor, is provided above building and directly connected to earth.”

[image of Common-mode choke]

Here is a simplified AC power diagram.

One is “what exactly is in a ‘surge protector’ ? ”

This one hit behind the barn.

This is where this question deviates from being a 'generic' question, and becomes more specific.

This is a photo where a lightning bolt took out a home's complete mains distribution box, and a lot of electronic gear as well.

Barnstars:

When the current is 200% of the rated value , it will “go open” (the link metal melts) and protect the device.

This is where the MOV conducts again, and dissipated the energy.

But… the neutral is now “floating” because of the 1 ohm resistance.

The other is “what does a “fuse” do?”

A fuse is a non-resetable over current circuit protector.

It’s been three xxx five werks, and there has been no response to my follow on query on his Commment to my answer.

One

Can the fuse protect the electronic devices from lightning instead of a surge protector.

For this case there are devices called Metal oxide varistors (MOV).

It seems Mohan does not understand the difference between a comment and an Answer.

At the secondary, it is 1000 times less.)turns ratio). If it gets hit with a 100,000 volt bolt of lightning then the voltage arrestors conduct and clamp the voltage down to line voltage, ( but a small amount leaks down the line). This is the problem.

So, it’s possible that these devices from Trip Lite have addition suppression devices, these ones seem to be sturdy.

Would individual surge supressors have save this equipment? most likely, since the surge supressor would take the jolt instead of the electronic components.

If the nominal power is 4,000 watts then the current at 230volts is 16 amps.

The MOV will conduct when the voltage exceeds 50% of line voltage.

This is the picture of an electronic coil of wire wound around a core of magnetic material.

(Dc diagram shown, AC is similar).

2024–10–14 [Omar Gharbi Omar Gharbi ]

These devices are installed between the “hot” and “neutral” and protective ground.

Because the load is inductive, the current lags the voltage.(by a bit).

2024–10–16 [ OO OLAOYE OYEBODE ]

At one ohm, the resistor has a maximum of 1 watt power.

P = e* I, so since I is 16 amps, then the voltage dropped is 1/16 volt or 0.0650 volts.

Fuses, on their own, then operate much slower than the MOV variable resistance, during the lightning strike.

There are two important concepts here.

An AC voltage/ current source, and an ac inductive load.

In schematic diagrams this is the symbol for a fuse:

Edit 2024–10.

So, the voltage could go up to 500 volts, and the fuse will not open up.

These are simplified answers to the original question, and does not change anything I wrote above.

A circuit breaker is similar, but is resettable.

This device then solves the entire problem.

This is 'the assistant's answer'

“ A surge suppressor is the one which is connected at the input supply so that when there is a sudden change voltage it bypasses thereby protecting the (circuit) and electronic components”

And this is the problem alone. Is the power supply in the equipmemt designed with a lightning strike in mind? Some yes, others, no.

It also is a device that limits the change in current flow.

Mohan forgets that a fuse is a one-time device, and needs to be replaced if it is tripped.

At least they know the answer if they wanted it.

Is the question then , "why buy a surge supressor, if the fuse alone protects the electronic circuits from a lightning bolt?".

Once the voltage goes over 0.0650 volts, then this fact can be used to amplify the difference, and turn the circuit breaker off , furthur down the line. Essentially that is what a RCD/GFCI does, it compares the incoming current, to the outgoing current, and if the difference between the two currents is over 5mA, then it trips the circuit breaker.
