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

Ohms to volts calculation formula with watts
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
