Determine expressions for and sketch v R ( t ) to scale versus time for the circuit of Figure P4.43. The circuit is operating in steady state with the switch closed prior to t=0. Consider the time interval −1≤t≤5 ms.
The circuit shown in Figure P4.39 is operating in steady state with the switch closed prior to t=0. Find expressions for i L ( t ) for t<0 and for t≥0. Sketch iL(t) to scale versus time
Consider the circuit of Figure P4.17, in which the switch instantaneously moves back and forth between contacts A and B, spending 2 seconds in each position. Thus, the capacitor repeatedly charges for 2 seconds and then discharges for 2 seconds. Assume that v C ( 0 )=0 and that the switch moves to position A at t=0. Determine v C ( 2 ), v C ( 4 ), v C ( 6 ), and v C ( 8 ).
