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?

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

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

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

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

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

One is “what exactly is in a ‘surge protector’ ? ”
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 this device (an Inductor) … impedes the rapid changes in the current.

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.
“ … to protect building, lightning arrestor, is provided above building and directly connected to earth.”
Because the load is inductive, the current lags the voltage.(by a bit).

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

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.

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.
But it can get overloaded, and no longer works.
He then describes the function of a fuse.
This is where this question deviates from being a 'generic' question, and becomes more specific.
This is the picture of an electronic coil of wire wound around a core of magnetic material.
These devices are installed between the “hot” and “neutral” and protective ground.
But during the surge, the fuse will not blow if it is a longer duration and lower value )10 to 50%).
At least they know the answer if they wanted it.
An AC voltage/ current source, and an ac inductive load.
There are two important concepts here.
He then asserts :
In schematic diagrams this is the symbol for a fuse:

A circuit breaker is similar, but is resettable.
Can the fuse protect the electronic devices from lightning instead of a surge protector.

The other is “what does a “fuse” do?”
There are three different concepts here that are getting confused.
eight
(Dc diagram shown, AC is similar).
[old diagram got deleted by accident]
A fuse is a non-resetable over current circuit protector.
but I think this circuit , shows a few more pieces.
I post the exact comment here.
Here is a simplified AC power diagram.
“ A fuse is a device which protects the (circuit) against overload and short circuit.”
This is 'the assistant's answer'
But… the neutral is now “floating” because of the 1 ohm resistance.
These are simplified answers to the original question, and does not change anything I wrote above.
If the nominal power is 4,000 watts then the current at 230volts is 16 amps.
First Sentence:
Edit 2024–10.
This is where the MOV conducts again, and dissipated the energy.
nine
Mohan forgets that a fuse is a one-time device, and needs to be replaced if it is tripped.
Fuses, on their own, then operate much slower than the MOV variable resistance, during the lightning strike.
For this case there are devices called Metal oxide varistors (MOV).
The MOV will conduct when the voltage exceeds 50% of line voltage.
so, what happens?
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?
Now when you have a certain ac resistance, then a current flows in a loop.
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.
The third is lightning and “how it gets conducted into a home.”
So, the voltage could go up to 500 volts, and the fuse will not open up.
