A resistor and inductor are connected to a 9.0 V battery by a switch as shown. The moment
the switch is closed, current flows through the circuit. The resistor has a resistance of R =
470 Q and the inductor has an inductance of L = 0.115 H.

The circuit below contains an inductor (L = 3 H) with an internal resistance R3 = 60 ohm. The other resistor values are R1 = 50 ohm and R2 = 60 ohm, and the battery has a voltage of 400 V. Immediately after the switch is closed, find the magnitude and direction of the conventional current through the battery, and find the voltage across the inductor.
Problem 3: An inductor with L = 8.5 H is in a closed circuit with I = 0.55 A (see the
diagram). When the switch is opened, the current goes to zero in At = 0.14 s.
