Question

Consider the circuit shown in Fig. 19–71, where all resistors have the same resistance R. At t = 0, with the capacitor C uncharged, the switch is closed. a) At t = 0, the three currents can be determined by analyzing a simpler, but equivalent, circuit. Draw this simpler circuit and use it to find the values of I_1, I_2, and I_3 at t = 0. b) At t = \infty, the currents can be determined by analyzing a simpler, equivalent circuit. Draw this simpler circuit and implement it in finding the values of I_1, I_2, and I_3 at t = \infty. c) At t = \infty, what is the potential difference across the capacitor?

Accepted Answer

a) I_1 = \dfrac{2\xi}{3R}, I_2 = I_3 = \dfrac{\xi}{3R} b) I_1 = I_2 = \dfrac{\xi}{2R}, I_3 = 0 c) I_3 = 0, V_c = \dfrac{\xi}{2}
