The electrical resistance is given by:
R = V / I
Corresponding units:
ohm (Ω) = volt (V) / ampere (A)
Where we have:
V: voltage
I: current
R: resistance
If the electric power and the voltage are know, then the total resistance can be determined by using:
R = V2 / P
If the electric power and the current are know, then the total resistance can be determined by:
R = P / I2
