How to Calculate the Voltage Across an Inductor

Voltage current through across capacitor

To calculate the voltage across an inductor, the formula is:

Formula for voltage across an inductor

All you have to know to calculate the voltage across the inductor is L, the Inductance of the Inductor which is expressed in units, Henry, and the derivative of the current going through the inductor.

If the current going through the inductor is 70sin(1000t) and its inductance is 50μH, what is the voltage across the inductor?
