Chapter 29, Problem 16Q

To determine

From where the transistor gets energy to increase the power.

Answer to Problem 16Q

Solution:

From the collector or emitter voltage source.

Explanation of Solution

Given:

A transistor can amplify the electronic signal, means it can increase the power of input signal.

The transistor gets the energy from the power supplied by the collector/emitter voltage source. The input signal regulates, how much current in the transistor and hence $h_{oe}=w$ much power is drawn from the collector’s voltage source.
