# How to Calculate the Current Through an Inductor

To calculate the current going through an inductor, the formula below is used:

All you must know to calculate the current going through an inductor is **L**, the inductance
of the inductor and the integral of the voltage that is across the inductor.

Note: Io is the initial current going through the inductor, if there is any.

**Example**

If the voltage across an inductor is 5cos(2000t)V and the inductance of the inductor is 5μH, what is the
current going through the inductor?

(Initial Conditions:Io=0A)
