Finding the Cathode and Testing the Diode
The cathode end is usually marked by a band on the body. Current flows when the anode is more positive than the cathode (forward bias) and is blocked when the connection is reversed. On a multimeter’s diode test, the forward reading shows the junction voltage drop and the reverse reading shows an open circuit.
From AC to DC
One diode in series with an AC supply passes only one half of each cycle, giving half-wave rectification. Four diodes in a bridge pass both halves the same way (full-wave), and a capacitor across the load smooths the output.
