Electric Current

The electric current is given by:

I = V / R

Corresponding units:
ampere (A) = volt (V) / ohm (Ω)

This formula is derived from Ohm's law. Where we have:
V: voltage
I: current
R: resistance

If the electric power and the total resistance are known, then the current can be determined by using the following formula:

I = √(P / R)

Corresponding units:
Ampere (A) = √(Watt (W) / Ohm (Ω))

Where P is the electric power.
