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 U0. Calculate the energy at t = RC and at t = 0.26 RC. Express the answers as fractions of the initial energy. (No units because the answers are a ratio of energy/energy.)
(C) Determine the power P(t) dissipated in the resistor. Calculate the power at t = RC and t = 0.26 RC. Express the answers as fractions of U0/?.
