How to convert Amps to Volts

Amps to volts calculation formula with watts

V(V) = P(W) / I(A)

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

So,

V = W / A
volts = watts / amps

For example:

Power (P) = 75W
Phase current (I) = 2,5A

Voltage (V) = 75W / 2,5A = 30V

Amps to volts calculation formula with ohms

V(V) = I(A) × R(Ω)

The voltage V in volts (V) is equal to the phase current I in amps (A), multiplied by the resistance R in ohms (Ω).

So,

V = A x Ω
volts = amps x ohms

For example:

Phase current (I) = 2,5A
Resistance (R) = 7Ω

Voltage (V) = 2,5A x 7Ω = 17,5V
