In this video we look at how to calculate resistance and impedance for a resistor and an inductor connected in series or what's known as an RL series circuit, which is a way of representing the behaviour of a coil. We also demonstrate how to draw an impedance triangle to scale, calculate current and voltages within the circuit and find the true power.
