You are given a 3.0 V battery, a resistor with value R = 1.0 kΩ, and an inductor with inductance L = 5.0 mH and minimal internal resistance compared to the given resistor. You are also given a simple ‘on-off’ switch. You connect the four devices in series.
a) Sketch the circuit.
b) What is the energy stored in the inductor after the switch has been closed for a long time?
