Discussion Forum : Bipolar Junction Transistors (BJT) - True or False (Q.No. 10)
10.
When troubleshooting a bipolar junction transistor using an ohmmeter, if one of the junctions reads low in both directions, the junction is shorted and the transistor is bad. If one of the junctions reads high in both directions, the junction is shorted and the transistor is good.

Both processes would mean that the transistor is good because for example for an NPN transistor when the positive probe is placed on the Base and negative to either Collector or Emitter it would read low on both since it would be forward biased. If the negative probe is placed on the Base and positive to either Collector or Emitter it would read high on both since it is now reverse biased.
