How to convert Ohms to Volts

Ohms to volts calculation formula with amps

V_(V) = I_(A) × R_(Ω)

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

So,

V = A × Ω
volt = amp × ohm

For example:

Current (I) = 0,5A
Resistance (R) = 30Ω

Voltage (V) = 0,5A x 30Ω = 15V

V_(V) = √ (P_(W) × R_(Ω))

The voltage V in volts (V) is equal to the square root of the power P in watts (W), multiplied by the resistance R in ohms (Ω).

So,

V = √ (W × Ω)
volt = √ (watt × ohm)

For example:

Power (P) = 10W
Resistance (R) = 6Ω

Voltage (V) = √ (10W x 6Ω) = 7,746V
