$$ Chapter $26-27$

Item $2$

A $8\mathrm{.}00F$ capacitor that is initially uncharged is connected in series with a $4\mathrm{.}00$ resistor and an emf source with $E=70\mathrm{.}0V$ and negligible internal resistance.

Part A

At the instant when the resistor is dissipating electrical energy at a rate of $300W,$ how much energy has been stored in the capacitor?
