# Energy to Charge a Capacitor

APPH12-HQZIX1

During Process 1 a capacitor is charged from zero to $100\ \mu\text{C}$ by applying a potential difference of $20\text{ V}$. During Process 2 the same capacitor is charged from $100\ \mu\text{C}$ to $200\ \mu\text{C}$ by increasing the potential difference from $20$ to $40 \text{ V}$.

Which of the following statements are true?

A

The capacitance equals $0.2\ \mu\text{F}$.

B

The capacitance equals $5\ \mu\text{F}$.

C

Process 1 added more energy to the capacitor than Process 2.

D

Process 2 added more energy to the capacitor than Process 1.
