Description
A resistance box and an air-core coil are used in an RL circuit. The inductance of the air-core coil can be calculated (if desired) and the time constant L/R calculated from the inductance and the resistance of the box. This can be compared with the experimental result. The signal source is a low-frequency square wave. See circuit below.
