Description:A resistance box and an air-core coil (from K2-27) 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, a square wave of about 2000 Hertz, is displayed on the upper trace, and the current in the RL circuit on the lower trace. See circuit above.
