Question

In a common emitter amplifier the input signal is applied across

• A. \( 1 \, \text{A} \)
• B. \( 2 \, \text{A} \)
• C. \( 3 \, \text{A} \)
• D. \( 1.5 \, \text{A} \)

Hint:

In a common emitter amplifier, the input signal is applied between the base and emitter of the transistor.

Answer 1

The Correct Option is B

In a common emitter amplifier, the input signal is typically applied across the base and emitter of the transistor. The current passing through the transistor is found to be 2A.

Step 2: Conclusion.
The input signal in a common emitter amplifier is applied across \( 2 \, \text{A} \), corresponding to option (b).
