Assume that the switch, S 1 , in Fig. 21-14 has been closed for more than five L / R time constants. If a1-M resistor is placed across the terminals of the switch, calculate
a. the approximate time constant of the circuit with S 1 open.
b. the peak inductor voltage, V L , when S 1 is opened.
c. how long it takes for the current to decay to zero after S 1 is opened (approximately).
a. the approximate time constant of the circuit with S 1 open.
