MAST Semiconductors Module Experiment 5 Alternating to Direct

This laboratory illustrates how diodes can be used to rectify alternating current. It uses galvanometer to determine the direction of current flow when an AC or DC current is applied to the circuit containing a diode in series with a resistor and a galvanometer.
