100%
You connect a battery, resistor, and capacitor as in the figure, where R = 16.0 Ω and C = 8.00 ×10−6 F. The switch S is closed at t = 0. When the current in the circuit has magnitude 3.00 A, the charge on the capacitor is 40.0 × 10−6 C.
(a) What is the emf of the battery?
(b) At what time t after the switch is closed is the charge on the capacitor equal to 40.0×10−6 C?
(c) When the current has magnitude 3.00 A, at what rate is energy being stored in the capacitor?
(d) When the current has magnitude 3.00 A, at what rate is energy being supplied by the battery?
