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?

He then describes the function of a fuse.
Now when you have a certain ac resistance, then a current flows in a loop.
These devices are installed between the “hot” and “neutral” and protective ground.
At one ohm, the resistor has a maximum of 1 watt power.
This is where the MOV conducts again, and dissipated the energy.

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

A circuit breaker is similar, but is resettable.

Because the load is inductive, the current lags the voltage.(by a bit).
So, the voltage could go up to 500 volts, and the fuse will not open up.
But… the neutral is now “floating” because of the 1 ohm resistance.
Are Americans really as uneducated and ignorant as portrayed in the media?
Mohan forgets that a fuse is a one-time device, and needs to be replaced if it is tripped.
He then asserts :

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

The bolt then partially travels down the line to your home.
What does a fuse do?
An AC voltage/ current source, and an ac inductive load.
I post the exact comment here.
These are simplified answers to the original question, and does not change anything I wrote above.

This is 'the assistant's answer'
the problem then depends on "how fast does the fuse operate?".
There are two important concepts here.
Has anyone tried bestiality and been caught?
This device then solves the entire problem.
The third is lightning and “how it gets conducted into a home.”

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.
“ 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 foolish atheists think their strange delusional theories are facts?
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.

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.
“ A fuse is a device which protects the (circuit) against overload and short circuit.”
(There is no concept of polarity, in the loop because the current changes direction 100 to 120 times a second (power frequency).
Barnstars:
So combined with a device called a MOV or Metal-oxide-resistor, then forms the 3rd part of a “surge suppressor “.
It seems Mohan does not understand the difference between a comment and an Answer.
OK, this is Mohan Rajaratnam’s definition of a Surge suppressor.
What is lightning?
Here is a simplified AC power diagram.
Edit 2024–10.
Can the fuse protect the electronic devices from lightning instead of a surge protector.
P = e* I, so since I is 16 amps, then the voltage dropped is 1/16 volt or 0.0650 volts.
There are three different concepts here that are getting confused.
But during the surge, the fuse will not blow if it is a longer duration and lower value )10 to 50%).
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.
In schematic diagrams this is the symbol for a fuse:
So, it’s possible that these devices from Trip Lite have addition suppression devices, these ones seem to be sturdy.
If the nominal power is 4,000 watts then the current at 230volts is 16 amps.
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.
But it can get overloaded, and no longer works.
The other is “what does a “fuse” do?”
but I think this circuit , shows a few more pieces.
“ … to protect building, lightning arrestor, is provided above building and directly connected to earth.”
This is where this question deviates from being a 'generic' question, and becomes more specific.
Would individual surge supressors have save this equipment? most likely, since the surge supressor would take the jolt instead of the electronic components.
He then describes Rainy Season and Lightning.
For this case there are devices called Metal oxide varistors (MOV).
Fuses, on their own, then operate much slower than the MOV variable resistance, during the lightning strike.
It also is a device that limits the change in current flow.
so, the loop of wire then, when put together with another loop reduces the ‘noise’ on a power line.
And this is the problem alone. Is the power supply in the equipmemt designed with a lightning strike in mind? Some yes, others, no.

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

First Sentence:
but this device (an Inductor) … impedes the rapid changes in the current.
A fuse is a non-resetable over current circuit protector.
