The switch in the circuit shown in Figure P 7.8-5 has been open for a long time before
Chapter 7, Problem P7.8-5(choose chapter or problem)
The switch in the circuit shown in Figure P 7.8-5 has been open for a long time before it closes at time t = 0. Determine the values of \(i_{\mathrm{R}}(0-)\) and \(i_{\mathrm{C}}(0-)\), the current in one of the \(20-\Omega\) resistors and in the capacitor immediately before the switch closes, and the values of \(i_{\mathrm{R}}(0+)\) and \(i_{\mathrm{C}}(0+)\), the current in that \(20-\Omega\) resistor and in the capacitor immediately after the switch closes.
