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?

This is where this question deviates from being a 'generic' question, and becomes more specific.
What does a fuse do?
One is “what exactly is in a ‘surge protector’ ? ”
At one ohm, the resistor has a maximum of 1 watt power.
So, it’s possible that these devices from Trip Lite have addition suppression devices, these ones seem to be sturdy.

what exactly is a ‘surge’ protector?

Can the fuse protect the electronic devices from lightning instead of a surge protector.
An AC voltage/ current source, and an ac inductive load.

Mohan forgets that a fuse is a one-time device, and needs to be replaced if it is tripped.
This is 'the assistant's answer'
It seems Mohan does not understand the difference between a comment and an Answer.

This device then solves the entire problem.

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.

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

A fuse is a non-resetable over current circuit protector.
What is it that gives a man who is a submissive cock sucker his most pleasure?
It also is a device that limits the change in current flow.
“ A fuse is a device which protects the (circuit) against overload and short circuit.”
This is where the MOV conducts again, and dissipated the energy.
But… the neutral is now “floating” because of the 1 ohm resistance.
Now when you have a certain ac resistance, then a current flows in a loop.

“ … to protect building, lightning arrestor, is provided above building and directly connected to earth.”
So combined with a device called a MOV or Metal-oxide-resistor, then forms the 3rd part of a “surge suppressor “.
When the current is 200% of the rated value , it will “go open” (the link metal melts) and protect the device.

Would individual surge supressors have save this equipment? most likely, since the surge supressor would take the jolt instead of the electronic components.
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.
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.
Barnstars:
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 circuit breaker is similar, but is resettable.
so, what happens?
He then describes the function of a fuse.
P = e* I, so since I is 16 amps, then the voltage dropped is 1/16 volt or 0.0650 volts.
(There is no concept of polarity, in the loop because the current changes direction 100 to 120 times a second (power frequency).
There are two important concepts here.
In schematic diagrams this is the symbol for a fuse:

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

At least they know the answer if they wanted it.
(Dc diagram shown, AC is similar).
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.
And this is the problem alone. Is the power supply in the equipmemt designed with a lightning strike in mind? Some yes, others, no.
But during the surge, the fuse will not blow if it is a longer duration and lower value )10 to 50%).
the problem then depends on "how fast does the fuse operate?".
The other is “what does a “fuse” do?”
These devices are installed between the “hot” and “neutral” and protective ground.

This one hit behind the barn.
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 voltage could go up to 500 volts, and the fuse will not open up.
so, the loop of wire then, when put together with another loop reduces the ‘noise’ on a power line.
Because the load is inductive, the current lags the voltage.(by a bit).
Edit 2024–10.
There are three different concepts here that are getting confused.

What is lightning?
The MOV will conduct when the voltage exceeds 50% of line voltage.
