The emitter-base junction of a transistor is ....... biased, while the collector-base junction is ....... biased.

Options

  1. Areverse, forward
  2. Breverse, reverse
  3. Cforward, forward
  4. Dforward, reverse

Correct answer

D. forward, reverse

Step-by-step solution

The emitter is always forward biased to enable the majority charge carriers to cross the emitter-base junction and collector-base function is in reverse biased to collect the charge carriers, so that current flows through the transistor. Hence, the emitter-base junction of a transistor is forward biased, while collector-base junction is reverse biased.
