Question
Which of the following can provide power gain?
Answer Options
- A) Transformer
- B) Transistor
- C) Reactor
- D) Resistor
Correct Answer: B
Explanation
The key function of a Transistor is its ability to take a small input signal (current or voltage) and use that to control a much larger flow of current or voltage, resulting in a larger output signal. This process is called amplification.
The ratio of the output signal power to the input signal power is the power gain (T6B11). A transistor is an active device capable of providing this power gain, making it the central component in all amplifiers and oscillators.
