This physics video tutorial provides a basic introduction into RL circuits which are made of inductors and resistors. It explains how to calculate the instantaneous current at any time as well as the maximum current after the switch has been closed for a long time. It discusses how to calculate the time constant given the inductance and the resistance and how to determine how many time constants is required for the inductor to be 99.4% charged. This video explains how to calculate the voltage across the inductor and the resistor as well as the battery. It explains how to determine the instantaneous rate at which energy is being consumed by the resistor and the inductor. The emf induced by the inductor is dependent on the rate at which the current is changing in the circuit. This video contains plenty of examples and practice problems.
