When a transistor is operating as a variable resistor it has transistance.

More Questions from Bipolar Junction Transistors (BJT)

• The polarity of VBE is such that it reverse biases the base-emitter junction.
• The voltage gain of a transistor is inversely proportional to the change in output current.
• This is a PNP transistor.
• The voltage measured from the collector to the emitter is the sum of the base-emitter voltage plus the collector-base voltage.
• In a BJT, the collector current is approximately equal to the base current.
• 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.
