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?

Why do people hate Nickelback so much? What makes them different from other popular bands like Linkin Park, Green Day, etc.? Is it just because they're Canadian or what?

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

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

While wearing high heels and walking heel to toe, when the toe box hit the floor there is a noise. How do I keep the noise just for the heel?

At least they know the answer if they wanted it.

This is 'the assistant's answer'

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

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

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

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

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

What's the difference between “ce”, “ça”, and “cela”, and when do I use each (French)?

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

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

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

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

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

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

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

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

How do I deal with autistic burnout/meltdown/shutdown when cooking?

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 other is “what does a “fuse” do?”

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

I post the exact comment here.

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.

He then describes the function of a fuse.

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

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

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

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

From an axiology/value theory point of view, how can one say that a diverse society is better than a uniform one, especially given the negative effects of diversity (racism, sectarian conflict, problems arising from extreme cultural relativism)?

so, what happens?

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

Why do most Indian women cuckold or cheat on their husbands?

what exactly is a ‘surge’ protector?

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

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

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

(Dc diagram shown, AC is similar).

What is lightning?

A circuit breaker is similar, but is resettable.

2024–10–11 [Victor Olarewsju Victor Olarewaju ]

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

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

2024–10–14 [Omar Gharbi Omar Gharbi ]

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

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

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

“ 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”

But it can get overloaded, and no longer works.

Can the fuse protect the electronic devices from lightning instead of 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.

a photo is worth a thousand words.

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

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

This one hit behind the barn.

There are three different concepts here that are getting confused.

What does a fuse do?

In schematic diagrams this is the symbol for a fuse:

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

He then asserts :

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

Here is a simplified AC power diagram.

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

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

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

There are two important concepts here.

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

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

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.
