## Charging and discharging of capacitor - Physics - eSaral

Hey, do you want to learn about the Charging and discharging of capacitors? If yes. Then you are at the right place. Charging and discharging of capacitors Charging When a capacitor C is connected to a battery through R then charging of capacitor takes place. The eqn. of emf at any time t is $R I+\frac{q}{C}=E$ $\frac{R d q}{d t}+\frac{q}{C}=E$ $\int_{0}^{Q} \frac{d q}{(C E-q)}$ $=-\int_{0}^{t} \frac{d t}{R C}$ This on solving gives $Q=Q_{0}\left(1-e^{-t / R C}\right)$ where $Q_{0}=C E$ Importan...
