125 volts is equal to how many amps?

Question

Here's a few more details. I blew a fuse in my house this morning. The new fuses that I have all have number of amps on them. The fuse that blew says 125 volts on it.

Answer 1

The two quantities are not equivalent. One is electric "pressure" and the other is electric "flow" (to use a water analogy.

Amps = volts / resistance

And resistance is the amount of load, the higher the resistance in ohms, the less load.

Answer 2

This is a math question?

Anyway, it is meaningless. It is like asking 5 pounds is equal to how many feet?

Volts and amps measure 2 different things. Volts measures (has different terms) voltage, electromotive force (EMF), potential difference. It is a more complicated concept, but think of it as related to the force between opposite charges. This force can cause an electric current.

Amps or ampere is a unit of electric current. 1 amp is q coulomb of charge (a certain number of electrons for example) passing a point in 1 second.

In a simple circuit, ohm's law relates the two: E=IR
E is voltage, I is current, and R is resistance in ohms.

Edit, still not a math question. You should have put it in repairs or something. The fuse should have an AMP rating on it as well as the voltage. The whole point of a fuse is to blow when it exceeds its amp rating. A hardware store could help you if you can't find the amp rating on the fuse. Or post a picture of it.

Answer 3

The other posters are right that volts and amps are different quantities. So hopefully the one you blew also has an amperage marked somewhere, in addition to the current. However, most household circuit breakers have a capacity of 15A, so this might be helpful information. I'd be careful, though, because if your house uses fuses, the wiring must be fairly old, and may not have the same capacity as a more modern house. For safety, it would be better to go with a smaller fuse than to go with a larger one if you are unsure. You want the fuse to blow before the wiring in your wall starts to smoke!

Answer 4

A fuse doesn't blow on voltage. Fuses work by disintegrating with too much heat, caused by the current.

The current through this fuse is dependent on the load of all your electrical things plugged into the outlets.

It probably states 125 volts for the same reason lamps tell you to use 60 watt light bulbs ... saves you money from having to constantly replace them.

Answer 5

volts and amps are not the same. they are not like foot and inches.

In fact they are related as follows

Volts/amps = resistance

Do check if the fuse you blew off has sthg written in amps also.

Answer 6

It would depend on how many ohms.

For instance

1 ohm with that would equal: 125 Amps
2 ohms with that would equal: 62.5 amps
3 ohms with that would equal: 41.66666666666amps
4 would equal: 31.25 amps

and so on like that.

Answer 7

to quote WIKIPEDIA.

The ampere (symbol: A) is the SI base unit of electric current. It is named after André-Marie Ampère, one of the main discoverers of electromagnetism.

The volt (symbol: V) is the SI derived unit of electric potential difference or electromotive force [1]. It is named in honor of the Italian physicist Alessandro Volta (1745–1827), who invented the voltaic pile, the first chemical battery.

So they are not the same thing, so you cannot convert volts to amps.

Answer 8

Depends on the amount of resistance in the circuit.

Volts = V
Current (ampere) = I
R = Resistance

I=V/R

Answer 9

8 amps

Answer 10

Good question:
V(volts)=I(amp) * R(ohms)
You need one more number... The load or resistance in ohms.
Good luck...
