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?

One

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

Why is my coworker suddenly being so mean towards then being nice like nothing happened? She is nice with everyone but me.

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

“ 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”

Why do we let ugly men exist?

so, what happens?

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.

a photo is worth a thousand words.

Any straight men had a gay experience in the past? What was it and how did you feel?

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

He then asserts :

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

Is it appropriate for parents to discipline their child in public if the child is being rude, disrespectful, and unruly towards them? Why or why not?

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

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

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

But it can get overloaded, and no longer works.

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

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

Why do some straight men like to suck dick but don't find other males attractive?

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.

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

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

Delta Force selection is originally based on SAS selection, so why is there no brutal jungle phase for Delta Force? It seems like it's based only on the Brecon Beacons section.

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

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

The other is “what does a “fuse” do?”

How is the legalization of same-sex marriage impacting societal norms in the USA?

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.

what exactly is a ‘surge’ protector?

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

What is the sum of X+XX+XXX+XXXX?

He then describes the function of a fuse.

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

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

I’m a man. Why do I always fantasize about men’s cock? I don’t want a relationship with the man, I just want to suck his cock.

(Dc diagram shown, AC is similar).

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

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

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

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

A circuit breaker is similar, but is resettable.

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

There are three different concepts here that are getting confused.

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

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.

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

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

This one hit behind the barn.

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

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

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

In schematic diagrams this is the symbol for a fuse:

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

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

There are two important concepts here.

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.

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

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

What does a fuse do?

At least they know the answer if they wanted it.

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

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

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

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

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

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.

Here is a simplified AC power diagram.

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

This device then solves the entire problem.

I post the exact comment here.

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

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.

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

He then describes Rainy Season and Lightning.

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

What is lightning?
