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. T= What is the final current flowing in the circuit (after switch #2 is closed and many time constants have passed)?
