To understand why option 'C' is the correct answer, let's first discuss the basic functioning of a transistor.
A transistor is a three-layer semiconductor device that consists of two pn-junctions. These pn-junctions are formed by bringing together two different types of semiconductor materials, namely P-type and N-type.
The three layers in a transistor are named as emitter, base, and collector. The emitter-base junction and the collector-base junction are the two pn-junctions in a transistor.
Now, let's analyze each option to determine the correct answer:
a) Both its emitter-base junction and collector-base junction are forward biased:
If both junctions are forward biased, it means that the P-side of the junction is connected to the positive terminal of the power supply and the N-side is connected to the negative terminal. In this biasing condition, the transistor will not act as a current amplifier. Instead, it will be in a saturation region, where the transistor operates as a switch.
b) Both its emitter-base junction and collector-base thin junction are reverse biased:
If both junctions are reverse biased, it means that the N-side of the junction is connected to the positive terminal of the power supply and the P-side is connected to the negative terminal. In this condition, no current flows through the transistor, and it does not act as a current amplifier.
d) Its emitter-base junction is reverse biased while the collector-base junction is forward biased:
If the emitter-base junction is reverse biased and the collector-base junction is forward biased, this biasing condition is known as the active region of operation. In this region, the transistor acts as a current amplifier. The reverse biased emitter-base junction allows the transistor to control the current flow from the emitter to the base. The forward biased collector-base junction allows the amplified current to flow from the collector to the emitter.
Therefore, option 'C' is the correct answer: Its emitter-base junction is forward biased while the collector-base junction is reverse biased.
