How to Calculate the Current Through a Capacitor

Current through Capacitor

To calculate current going through a capacitor, the formula is:

Formula for calculating current through a capacitor

All you have to know to calculate the current is C, the capacitance of the capacitor which is in unit, Farads, and the derivative of the voltage across the capacitor. The product of the two yields the current going through the capacitor.

If the voltage of a capacitor is 3sin(1000t) volts and its capacitance is 20μF, then what is the current going through the capacitor?
