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?

Fuses, on their own, then operate much slower than the MOV variable resistance, during the lightning strike.
But during the surge, the fuse will not blow if it is a longer duration and lower value )10 to 50%).
What makes you feel guilty the most?
Here is a simplified AC power diagram.
At least they know the answer if they wanted it.
So combined with a device called a MOV or Metal-oxide-resistor, then forms the 3rd part of a “surge suppressor “.

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

An AC voltage/ current source, and an ac inductive load.
This is 'the assistant's answer'
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.

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

He then asserts :
But… the neutral is now “floating” because of the 1 ohm resistance.
the problem then depends on "how fast does the fuse operate?".
How do flat earthers explain the Earth being stationary? Is this concept considered impossible?
And this is the problem alone. Is the power supply in the equipmemt designed with a lightning strike in mind? Some yes, others, no.
Because the load is inductive, the current lags the voltage.(by a bit).

What is the story of how you met your spouse?
“ 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”
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 it can get overloaded, and no longer works.

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

What's the biggest myth about illegal immigrants?
Mohan forgets that a fuse is a one-time device, and needs to be replaced if it is tripped.
This is the picture of an electronic coil of wire wound around a core of magnetic material.
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.

A fuse is a non-resetable over current circuit 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.
Can the fuse protect the electronic devices from lightning instead of a surge protector.

In schematic diagrams this is the symbol for a fuse:
These devices are installed between the “hot” and “neutral” and protective ground.
A circuit breaker is similar, but is resettable.
There are two important concepts here.
but I think this circuit , shows a few more pieces.
When the current is 200% of the rated value , it will “go open” (the link metal melts) and protect the device.
First Sentence:
[old diagram got deleted by accident]
(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?
“ A fuse is a device which protects the (circuit) against overload and short circuit.”
So, the voltage could go up to 500 volts, and the fuse will not open up.
This is where this question deviates from being a 'generic' question, and becomes more specific.

OK, this is Mohan Rajaratnam’s definition of a Surge suppressor.
The other is “what does a “fuse” do?”
Now when you have a certain ac resistance, then a current flows in a loop.
Is the question then , "why buy a surge supressor, if the fuse alone protects the electronic circuits from a lightning bolt?".
what exactly is a ‘surge’ protector?
What does a fuse do?
This one hit behind the barn.
“ … to protect building, lightning arrestor, is provided above building and directly connected to earth.”
For this case there are devices called Metal oxide varistors (MOV).
If the nominal power is 4,000 watts then the current at 230volts is 16 amps.
It seems Mohan does not understand the difference between a comment and an Answer.
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.
One is “what exactly is in a ‘surge protector’ ? ”
I post the exact comment here.
so, what happens?
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.
At one ohm, the resistor has a maximum of 1 watt power.
These are simplified answers to the original question, and does not change anything I wrote above.
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.

The third is lightning and “how it gets conducted into a home.”
The MOV will conduct when the voltage exceeds 50% of line voltage.
but this device (an Inductor) … impedes the rapid changes in the current.

Would individual surge supressors have save this equipment? most likely, since the surge supressor would take the jolt instead of the electronic components.
So, it’s possible that these devices from Trip Lite have addition suppression devices, these ones seem to be sturdy.
It also is a device that limits the change in current flow.
