Charge-Storage Device A capacitor is a two-terminal device that can store electric charge. In a linear capacitor, the amount of charge stored is proportional to the voltage across the device.
For a particular device the proportionality is q (t) = 10 -7 v (t). If v (t) = 0 for t -5000t) for t ≥ 0, find the energy stored in the device at t = 100 μs.
