Bipolar Junction Transistors (BJT) - Technical MCQs

Q1:

VCE approximately equals ________ when a transistor switch is cut off.

A VCC

B VB

C 0.2 V

D 0.7 V

ANS:A - VCC

VCE means output voltage between collector and emitter. When the transistor is cutoff then supply voltage (Vcc) is the output voltage.

When the transistor is in ON state then the output voltage is 0.
