Question

13(a). An inductor, battery, resistance, and ammeter and switch are connected in series. If the switch, initially open, is now closed, what is the current's final value? a. zero b. battery voltage divided by inductance c. battery voltage times inductance d. battery voltage divided by resistance e. Current is doubled f. Current is half g. Current is a factor times exp(-tc/t) where tc is the time constant 13(b). A 13-V battery is connected in series with a switch, resistor and coil. If the circuit's time constant is 1.2 × 10^-4 s and the final steady current after the switch is closed becomes 2.5 A, what is the value of the inductance? a. 3.9E-3 H b. 6.2E-4 H c. 2.3E-1 H d. 2.7E-3 H e. 2.3E-5 H
