Given below are two statements:
Statement I: For a transistor to operate as an amplifier, its emitter-base junction is forward biased and collector-base junction is reverse biased.
Statement II: In a common emitter (CE) configuration amplifier, the output voltage is in phase with the input voltage. Choose the correct answer from the options given below:
Options:
Answer:
C
Solution:
Statement I is true. This biasing condition (forward-biased emitter-base, reverse-biased collector-base) is essential for active region operation, which is required for amplification.
Statement II is false. In a common emitter amplifier, the output voltage (at the collector) is out of phase with the input voltage (at the base). This is a characteristic phase inversion.
