Question

To be in active state, emitter-base junction of a transistor is _______ biased while the collector-base junction is ________.

• A. reverse, forward
• B. reverse, reverse
• C. forward, forward
• D. forward, reverse

Answer 1

The correct option is D forward, reverse

The emitter base junction is forward biased while collector base junction is reversed biased for the transistor to be working in the active state. As the first junction is forwardly biased, majority carries the current and goes to base but to reach the collector the second junction has to be reversed biased.
