A series RL circuit consists of a 6.3 volt battery, a 175 ohm resistor and an inductor.

(a) If the battery has been connected for a long time interval, what is the current in the circuit?

(b) The battery is then removed from the circuit, so only the resistor and the inductor are connected in series. What is the inductance of the inductor if the current drops to half of its peak value in 2.00 ms?

(c) The current is then allowed to decrease to approximately zero and the battery is then reconnected. What time interval is required for the energy stored in the inductor to reach 90 percent of its maximum value?

a 10-volt battery connected across a parallel combination of a 100 (ohm) fixed resistor and a variable resistor R. It can be shown that the total current in the circuit I (in amperes, A) is the following function of the variable resistor R (in ohms): I= ((100+R)/10R) If the variable resistance is decreased at a rate of 5 ohm/s, calculate the rate of change in the current with time when the variable resistance is 50 ohms.
