Notes:
•When you measure the resistance of a component in a circuit, disconnect one side of the component you are testing. This prevents other components in the circuit from interfering with the reading.
•When you try to identify cathode and anode ends or the type of transistor (PNP or NPN), the actual polarity of the meter’s voltage is the opposite of the polarity suggested by the test probes’ color. The red test probe is the nega- tive source, and the black test probe is positive.
