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?

P = e* I, so since I is 16 amps, then the voltage dropped is 1/16 volt or 0.0650 volts.
But it can get overloaded, and no longer works.

A fuse is a non-resetable over current circuit protector.
Mohan forgets that a fuse is a one-time device, and needs to be replaced if it is tripped.

Have you ever been forced into bestiality?
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.
These are simplified answers to the original question, and does not change anything I wrote above.

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 I think this circuit , shows a few more pieces.
If the nominal power is 4,000 watts then the current at 230volts is 16 amps.

He then asserts :
The bolt then partially travels down the line to your home.
There are three different concepts here that are getting confused.
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.
He then describes the function of a fuse.
This is where the MOV conducts again, and dissipated the energy.

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?".

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 least they know the answer if they wanted it.

But… the neutral is now “floating” because of the 1 ohm resistance.
“ 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”
(Dc diagram shown, AC is similar).

Now when you have a certain ac resistance, then a current flows in a loop.
It’s been three xxx five werks, and there has been no response to my follow on query on his Commment to my answer.
So combined with a device called a MOV or Metal-oxide-resistor, then forms the 3rd part of a “surge suppressor “.

So, it’s possible that these devices from Trip Lite have addition suppression devices, these ones seem to be sturdy.
Is the question then , "why buy a surge supressor, if the fuse alone protects the electronic circuits from a lightning bolt?".
In schematic diagrams this is the symbol for a fuse:

what exactly is a ‘surge’ protector?
When the current is 200% of the rated value , it will “go open” (the link metal melts) and protect the device.
In space, no one can hear you scream — But it still gets incredibly noisy - Salon.com
So, the voltage could go up to 500 volts, and the fuse will not open up.
Because the load is inductive, the current lags the voltage.(by a bit).
The third is lightning and “how it gets conducted into a home.”
What is the best way to get revenge on people who hurt you?
so, what happens?
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.
The other is “what does a “fuse” do?”

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

Would individual surge supressors have save this equipment? most likely, since the surge supressor would take the jolt instead of the electronic components.
These devices are installed between the “hot” and “neutral” and protective ground.
“ A fuse is a device which protects the (circuit) against overload and short circuit.”
It also is a device that limits the change in current flow.

OK, this is Mohan Rajaratnam’s definition of a Surge suppressor.
but this device (an Inductor) … impedes the rapid changes in the current.
What does a fuse do?
He then describes Rainy Season and Lightning.
There are two important concepts here.
And this is the problem alone. Is the power supply in the equipmemt designed with a lightning strike in mind? Some yes, others, no.
The MOV will conduct when the voltage exceeds 50% of line voltage.
It seems Mohan does not understand the difference between a comment and an Answer.
For this case there are devices called Metal oxide varistors (MOV).
One is “what exactly is in a ‘surge protector’ ? ”

At one ohm, the resistor has a maximum of 1 watt power.
A circuit breaker is similar, but is resettable.
This device then solves the entire problem.

so, the loop of wire then, when put together with another loop reduces the ‘noise’ on a power line.
Can the fuse protect the electronic devices from lightning instead of a surge protector.
An AC voltage/ current source, and an ac inductive load.
What is lightning?
(There is no concept of polarity, in the loop because the current changes direction 100 to 120 times a second (power frequency).
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.
