The current in a 100 µF capacitor is shown below. If capacitor is initially uncharged, then the waveform for the voltage across it is—
Correct Option: D
Voltage across capacitor,
| V = |  | t | i dt | C | 0 |
| = | | 2 × 10–3 | 10 × 10–3 dt | 100 × 10–6 | 0 |
| = | = .2 V | 100 × 10–6 |
This 0.2 V is increases linearly from 0 to 0.2 V up to 2 ms. after that capacitor holds constant voltage i.e. 0.2 V.
Hence alternative (D) is the correct choice.
