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 one hit behind the barn.

He then describes the function of a fuse.

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

Simulation reveals emergence of jet from binary neutron star merger followed by black hole formation - Phys.org

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.

So, it’s possible that these devices from Trip Lite have addition suppression devices, these ones seem to be sturdy.

What do you think about me (Aditya Krishna)?

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.

How are max different from medical and minimum security prisons?

It seems Mohan does not understand the difference between a comment and an Answer.

(There is no concept of polarity, in the loop because the current changes direction 100 to 120 times a second (power frequency).

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.

How many women have accidentally pooped their pants and became turned on afterwards?

(Dc diagram shown, AC is similar).

At one ohm, the resistor has a maximum of 1 watt power.

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

Is it true that most women like alpha males?

If the nominal power is 4,000 watts then the current at 230volts is 16 amps.

An AC voltage/ current source, and an ac inductive load.

what exactly is a ‘surge’ protector?

If we do not know the name of the father of a child, e.g. a foundling, an illegitimate, etc., then to whom should the bin or the binti of the child's name be applied?

This is 'the assistant's answer'

There are two important concepts here.

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

What is the typical mentality of the Indian society?

Barnstars:

I post the exact comment here.

Can the fuse protect the electronic devices from lightning instead of a surge protector.

Do you consider yourself pretty?

Why do flat Earthers still exist even though it is scientifically proven that the Earth is spherical?

Here is a simplified AC power diagram.

“ 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”

In schematic diagrams this is the symbol for a fuse:

What is lightning?

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

Can you explain the ongoing conflict between Palestine and Israel? Why does it appear that Israel has been more successful in the conflict?

The MOV will conduct when the voltage exceeds 50% of line voltage.

“ … to protect building, lightning arrestor, is provided above building and directly connected to earth.”

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.

Do women lack the mental strength to succeed at STEM? There seems to be few women at STEM and more women leave STEM after a time of working at it. How can it be just sexism if women aren't banned from entering?

First Sentence:

Now when you have a certain ac resistance, then a current flows in a loop.

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

Why does my private parts itch so much during certain periods?

But it can get overloaded, and no longer works.

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%).

This device then solves the entire problem.

It’s been three xxx five werks, and there has been no response to my follow on query on his Commment to my answer.

He then asserts :

Because the load is inductive, the current lags the voltage.(by a bit).

2024–10–11 [Bobby Sanchez Bobby Sanchez ].

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

The bolt then partially travels down the line to your home.

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 where this question deviates from being a 'generic' question, and becomes more specific.

But… the neutral is now “floating” because of the 1 ohm resistance.

Mohan forgets that a fuse is a one-time device, and needs to be replaced if it is tripped.

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

These are simplified answers to the original question, and does not change anything I wrote above.

He then describes Rainy Season and Lightning.

2024–10–16 [ OO OLAOYE OYEBODE ]

so, what happens?

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.

For this case there are devices called Metal oxide varistors (MOV).

Edit 2024–10.

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.

2024–09–27 [ Mohan Rajaratnam Mohan Rajaratnam ] . Thinks you can get free electricity from nothing : Mohan Rajaratnam's answer to Is it possible to generate free electricity at home using a magnet or other low-cost methods? If so, how does it work?

At least they know the answer if they wanted it.

This is the picture of an electronic coil of wire wound around a core of magnetic material.

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 I think this circuit , shows a few more pieces.

So, the voltage could go up to 500 volts, and the fuse will not open up.

A circuit breaker is similar, but is resettable.

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.”

The other is “what does a “fuse” do?”

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

There are three different concepts here that are getting confused.

One

So combined with a device called a MOV or Metal-oxide-resistor, then forms the 3rd part of a “surge suppressor “.

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.

What does a fuse do?

The third is lightning and “how it gets conducted into a home.”

but this device (an Inductor) … impedes the rapid changes in the current.

A fuse is a non-resetable over current circuit protector.
