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?

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

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

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

What are the differences between fuzzy, intuitionistic, and paraconsistent logic? Which one is considered the most useful and why?

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

He then asserts :

There are two important concepts here.

Why does a narcissist act like it's nothing when they hurt you?

What is lightning?

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

One

What makes you think that former U.S. President Donald Trump's legal team has already been laying the groundwork for an appeal in the hush money trial?

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

A circuit breaker is similar, but is resettable.

This device then solves the entire problem.

Why do I keep waking up at 4 AM?

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

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.

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

What melts your heart every time without fail?

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

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

eight

Recently, I cleared my JP Morgan coding round. Next, I received mail for a video interview. What kind of questions are asked in this round? How do I prepare myself?

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

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.

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

What is the most ridiculous obviously false verse in the Bible?

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

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.

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

I read this: "Putin is a brilliant, courageous, ingenious, determined, beloved, and incredible modern leader. He is currently the world’s most effective and strong leader, the best the world has seen in centuries." What do you think about this?

In schematic diagrams this is the symbol for a fuse:

The Roman Empire at the time of Christ kept meticulous records. Why then, is there no record of the trial of Jesus?

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

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

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

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

There are three different concepts here that are getting confused.

Why are most people broke?

Here is a simplified AC power diagram.

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

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

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.

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

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

He then describes the function of a fuse.

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

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

This is 'the assistant's answer'

The other is “what does a “fuse” do?”

First Sentence:

At least they know the answer if they wanted it.

(Dc diagram shown, AC is similar).

I post the exact comment here.

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

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

What does a fuse do?

[old diagram got deleted by accident]

He then describes Rainy Season and Lightning.

Edit 2024–10.

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

so, what happens?

nine

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

Barnstars:

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

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.

“ 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”

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?

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

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

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

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

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

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

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.

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

a photo is worth a thousand words.

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

But it can get overloaded, and no longer works.

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

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

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

This one hit behind the barn.

what exactly is a ‘surge’ protector?
