Chapter 8, Problem 21(choose chapter or problem)
We can safely assume the switch in the circuit of Fig. 8.59 was closed a very long time prior to being thrown open at t = 0. (a) Determine the circuit time constant. (b) Obtain an expression for \(i_1(t)\) which is valid for t > 0. (c) Determine the power dissipated by the \(12\ \Omega\) resistor at t = 500 ms.
