How many amps are in 3 volts?

Answer 1

You're talking about two different measurements. Voltage is not equal to current (amps) nor is there any correlation between the two.

If you know the amount of watts the device uses, you can divide the watts consumed, by the voltage to get a rough estimate of the amps being drawn.

For example, a 1000 watt microwave running at 120 V will draw 8.3 amps.

AnswerThe formula is U = R*I, U (voltage in volts), I (flowrate in ampère), and as you see... you first need to know what R (resistance in ohm) you have... the you calculate U/R = I, that's all. Answer

There are no volts in amperes. They measure different quantities. Your question is like asking, "How many kilometres are there in 2.5 kilograms?" In other words, it is nonesense!

Answer 2

1 amp (abbreviation of ampere) is the measure of the flow of electricity through a resistance of 1 ohm with the emf (electromotive force) of 1 volt.

The number of amps flowing in an electrical circuit is proportional to the voltage divided by the resistance.

Answer 3

If you know Ohm's law, then you see that the value for the resistor R is missing.

Assuming the value for the resistor R = 10 ohms:

volts = (resistance in ohms) times (current in amps)

so:

volts = 10 ohms times 3 amps = 30 volts.

Answer #2:

If 'amps' and 'volts' were just different multiples of the same thing, there would be

no need for two different names.

The question is a lot like asking "How many yards are in 1 week ?"

"Volts" is a measure of the electrical 'pressure' between two points, that makes

current want to flow between them.

"Amps" is a measure of how much current actually flows as a result of the volts.

It depends on what's between the two points.

For example, if there's a pressure of some volts between two points, there could be

almost no current ... zero amps ... if there's nothing between the points to carry

current, or there could be very large current ... many amps ... if you connect a copper

wire between them, or accidentally drop your screwdriver or wrench across them.
