Question

Energy and Power in an RC Circuit. See the figure. With the switch in position A, the capacitor becomes charged. After a long time, the capacitor charge approaches q = C?. Now, suppose the capacitor is fully charged, when, at time t = 0, the switch is moved from A to B. (A) Determine the charge $q(t)$ and current $i(t)$ for t > 0. (B) Determine the energy of the capacitor $U(t)$ as a function of time t. The initial energy, at t = 0, is $U_0$. Calculate the energy at t = RC and at t = 0.56 RC. Express the answers as fractions of the initial energy. (No units because the answers are a ratio of energy/energy.) Submit Answer Tries 0/25 (C) Determine the power $P(t)$ dissipated in the resistor. Calculate the power at t = RC and t = 0.56 RC. Express the answers as fractions of $U_0/T$. Submit Answer Tries 0/25 (D) Determine the integrated power (the integral of $P(t')$ from t' = 0 to t). Calculate the integrated power for t = RC and t = 0.56 RC. Express the answers as fractions of $U_0$. Submit Answer Tries 0/25
