Multiple choice

In the transistor amplifier circuit shown in the figure below, $\beta_{DC} = 60, V_{BE} = 0.7V, h_{ie} \rightarrow \infty, h_{fe} \rightarrow \infty$ The capacitance Cc can be assumed to be infinite.

If $\beta_{DC}$ is increased by 10%, the collector-to-emitter voltage drop (Note: The ground has been shown by the symbol $\nabla$.)

  1. increases by less than or equal to 10%

  2. decreases by less than or equal to 10%

  3. increases by more than 10%

  4. decreases by more than 10%
