When a transistor amplifier having current gain of `75` is given an input signal, `V_(I) = 2 sin (157 t + pi//2)`, the output signal is found to be `V
When a transistor amplifier having current gain of `75` is given an input signal, `V_(I) = 2 sin (157 t + pi//2)`, the output signal is found to be `V_(o) = 200 sin(157 t + 3pi//2)`. The transistor is connected as :
A. a common base amplifier
B. a common collector amplifier
C. an oscillator
D. a common emitter amplifier

Correct Answer - D
There is a phase difference of `pi` between `V_i` and `V_o` in a CE amplifier.
