What exactly is the difference between a surge protector and a fuse? Can a fuse protect the electronic devices from lightning instead of surge protector?

At least they know the answer if they wanted it.

Why cant school buses ditch kids who are late to the bus at the school? Like on the way home, if a kid is late when all the others arrived to the bus on time, why cant they leave the late kid behind since its not fair to the on time kids to wait?

But it can get overloaded, and no longer works.

what exactly is a ‘surge’ protector?

There are three different concepts here that are getting confused.

What is your wildest experience in Bangalore that you haven’t told anyone?

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

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

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

Why are so many young teenage boys misogynistic? Where do they get these attitudes from?

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

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

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.

I see lots of pictures of women who have huge clits are they real or what?

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

a photo is worth a thousand words.

What factors may contribute to intelligent individuals identifying as Republican rather than Democrat in the United States today?

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.

Now when you have a certain ac resistance, then a current flows in a loop.

Why did you put a guy’s dick in your mouth the first time?

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

First Sentence:

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

If a guy is attracting a bunch of what he believes to be "ugly" women, is he crushing the dating game?

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

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

What discoveries in AI research have changed our understanding of intelligence evolution?

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

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.

What should I do? I'm 17 and I'm dating a 23-year-old guy.

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

Here is a simplified AC power diagram.

“ 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”

Is it common for girlfriends to have close male friends who are single and not related to them?

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

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

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

Why does my vagina and around my butthole itch? I don't have weird discharge and I'm still a virgin.

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

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

This one hit behind the barn.

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

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

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

[old diagram got deleted by accident]

He then describes Rainy Season and Lightning.

so, what happens?

He then describes the function of a fuse.

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.

He then asserts :

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.

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

There are two important concepts here.

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

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

(Dc diagram shown, AC is similar).

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

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.

2024–10–11 [Bobby Sanchez Bobby Sanchez ].

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

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

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

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

The other is “what does a “fuse” do?”

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

A circuit breaker is similar, but is resettable.

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.

I post the exact comment here.

This device then solves the entire problem.

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

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

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

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

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

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

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

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

What is lightning?

What does a fuse do?

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

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

This is 'the assistant's answer'

In schematic diagrams this is the symbol for a fuse:
