Vedclass · Answer

(A) The work done $W$ in charging a capacitor is equal to the potential energy $U$ stored in it.The formula for energy stored in a capacitor is $W = U = \frac{Q^2}{2C}$.Given:Charge $Q = 8 	imes 10^{-18} 	ext{ C}$Capacitance $C = 800 \mu	ext{F} = 800 	imes 10^{-6} 	ext{ F} = 8 	imes 10^{-4} 	ext{ F}$.Substituting the values:$W = \frac{(8 	imes 10^{-18})^2}{2 	imes 8 	imes 10^{-4}}$$W = \frac{64 	imes 10^{-36}}{16 	imes 10^{-4}}$$W = 4 	imes 10^{-32} 	ext{ J}$.

Work done in placing a charge of $8 \times 10^{-18} \text{ C}$ on a capacitor of capacitance $800 \mu\text{F}$ is . . . . . . .
