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?

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

(Dc diagram shown, AC is similar).

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

Have you ever had your crush reject you, and then later you all dated and married?

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.

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.

Dont you think we should put Project 2025 into full force to completely decimate the evil and corrupt Democratic party? The answer is yes.

The other is “what does a “fuse” do?”

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

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

Why are men obsessed with breasts and their size? I don't quite see women being obsessed with the penis - Why is this so?

First Sentence:

What does a fuse do?

There are two important concepts here.

Are there really people who still believe the Earth is flat?

What is lightning?

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.

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

What are examples of real life forced feminization?

One

but I think this circuit , shows a few more pieces.

In schematic diagrams this is the symbol for a fuse:

How can MeTV Toons compete with other national broadcast TV networks?

He then describes Rainy Season and Lightning.

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

These devices are installed between the “hot” and “neutral” and protective ground.

What factors may contribute to intelligent individuals identifying as Republican rather than Democrat in the United States today?

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

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.

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

Why did Cartman love Heidi purely with heart, her being the first one he ever did, but then one day Butters tells him that all women are manipulative and then he began to believe that she was a bad person and pretended to be a victim?

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

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

This device then solves the entire problem.

Why do I feel so tired all the time even after a good night’s sleep?

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

It also is a device that limits the change in current flow.

He then describes the function of a fuse.

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

There are three different concepts here that are getting confused.

2024–10–10[John johnson John Johnson ]

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

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

what exactly is a ‘surge’ protector?

This one hit behind the barn.

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

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

He then asserts :

OK, this is Mohan Rajaratnam’s definition 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.

This is 'the assistant's answer'

But during the surge, the fuse will not blow if it is a longer duration and lower value )10 to 50%).

Barnstars:

so, what happens?

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

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.

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

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

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

At least they know the answer if they wanted it.

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

[old diagram got deleted by accident]

“ A fuse is a device which protects the (circuit) against overload and short circuit.”

[image of Common-mode choke]

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

I post the exact comment here.

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

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

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

2024–10–16 [ OO OLAOYE OYEBODE ]

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

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

A circuit breaker is similar, but is resettable.

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

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

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

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.

But it can get overloaded, and no longer works.

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

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

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

Would individual surge supressors have save this equipment? most likely, since the surge supressor would take the jolt instead of the electronic components.
