Question

A Capacitor is a circuit component that stores energy and can be charged when current flows through it. A current of 2A flows through a capacitor that has an initial charge of 2?C (micro Coulombs). After two microseconds, what is the magnitude of the net electric charge (in ?C) of the capacitor?

Derive an equation for charge(q) in term of current then solve:

$q(t)=\int\limits^\tau_{\tau_0} {i(t)} \, d\tau+q_0$

Use the equation above to solve for your net charge.
