In a transistor (common emitter configuration) the ratio of power gain to voltage gain is ( and are current ratios)

Correct answer

3

Step-by-step solution

The power gain is defined as A_p = A_v A_i , where A_v is voltage gain and A_i is current gain. For a common emitter configuration, the current gain equals , so A_i = . Substituting gives A_p = A_v . The ratio of power gain to voltage gain is therefore A_p A_v = . Final answer:
