Diodes
• What is a diode? A diode acts like a one way
valve, allowing current to flow in only one direction.
See Figure 7.66.
• Which way does this electrical check-valve work?
There will be a band on one end of the diode. The
band indicates the negative side of the diode
• Most DMMs have the ability to test a diode.
Testing a diode:
1. Isolate the diode in the circuit.
2. Set the DMM to the diode or
Ω scale.
See Figure 7.67.
3. Attach the negative lead of the DMM to the side of
the diode with a band on it.
4. Place the positive lead on the other side of the diode.
5. There should be continuity. See Figure 7.68.
