Question

how to convert ampere into volt

Answer 1

You can calculate volts from amps and wattsor ohms, but you can't convert amps to volts since volt and amp units represent different quantities.

Amps to volts calculation with watts

The voltage V in volts (V) is equal to the power P in watts (W), divided by the current I in amps (A):

V(V) = P(W) / I(A)

So

volt = watt / amp

or

V = W / A

Example

What is the voltage supply of an electrical circuit that has power consumption of 45 watts and current flow of 3 amps?

The voltage V is equal to 45 watts divided by 3 amps:

V = 45W / 3A = 15V

Amps to volts calculation with ohms

The voltage V in volts (V) is equal to the current I in amps (A), times the resistance R in ohms (Ω):

V(V) = I(A) × R(Ω)

So

volt = amp × ohm

or

V = A × Ω
