Consider a series RC circuit as in the figure below for which R = 7.00 MQ, C = 8.00 UF, and & = 31.0 V. S R + E A (a) Find the time constant of the circuit. S (b) What is the maximum charge on the capacitor after the switch is thrown closed? HC (c) Find the current in the resistor 10.0 s after the switch is closed.Three identical 100.0-W, 120-V lightbulbs are connected across a 120-V power source as shown in in the figure below. Assume that the resistance of each bulb is constant (even though in reality the resistance increases markedly with current). R1 120 V R2 R3 A (a) Find the total power supplied by the power source. W (b) Find the potential difference across each lightbulb. AV, = AV, = V AV2 = V
