+1 862 207 3288 A solenoid having an inductance of 6.30 µH is connected in series with a 1.20 k? resistor. (a) If a 14.0 V battery is connected across the pair, how long will it take for the current through the resistor to reach 80.0% of its final value? (b) What is the current through the resistor at time t = 1.0tL?
