[#131] The amplifier circuit shown below uses a silicon transistor. The capacitors C C and C E can be assumed to be short at signal frequency and the effect of output resistance r 0 can be ignored. If C E is disconnected from the circuit, which one of the following statements is TRUE?
Correct Answer
(A) The input resistance R i increases and voltage gain A i decreases
[#132] The current gain of bipolar transistor drops at high frequency because of
Correct Answer
