In the circuit shown in the figure, the switch #2 can be toggled to either position a or b. In position
a, and with switch #1 also closed, the inductor (L) and resistor are connected to the source of emf (
&= 16 V). At the moment the switch closes, current begins to flow in the circuit. Given that L =
230 mH and R = 60 2, What is the time constant (7) that describes this charging process? Note
that 1 mH =
10-³ H.
