Chapter 26, Problem 49P

(II) Consider the circuit shown in Fig. 26–60, 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. Identify this simpler circuit and use it to find the values of I₁, I₂, and I₃ at t = 0. (b) At t = ∞, the currents can be determined by analyzing a simpler, equivalent circuit. Identify this simpler circuit and implement it in finding the values of I₁, I₂, and I₃ at t = ∞. (c) At t = ∞, what is the potential difference across the capacitor?
