For the circuit in Problem 60, what is the current through the circuit (a) just after the switch is closed and (b) after the switch has been closed for a very long time?

(reference problem 60)

Consider the RC circuit in Figure P19.60, with and When the switch is closed, the current will vary with time as sketched in Figure 19.30A. What is the time constant for the circuit in Figure P19.60? Hint: Use equivalent circuit ideas to “reduce” this circuit to a form that looks like Figure 19.29.

(reference figure 19.29 and 19.30)
