A solenoid having an inductance of 9.44 uH is connected in series with a 0.927 kQ resistor. (a) If a 12.0 V battery is connected across the pair, how long will it take in seconds for the current through the resistor to reach 87.5% of its final value? (b) What is the current through the resistor at a time t= 1.00T?
