In an experiment of C E configuration of n - p - n transistor, the transfer characteristics are observed as given in figure. If the input resistance is 200 Ω and output resistance is 60 Ω , the voltage gain in this experiment will be _____ .
Correct answer
0
Step-by-step solution
Voltage gain, A V = ? Input Resistance = 200   Ω Output Resistance = 60   Ω β = Δ I C Δ I B = 5 - 0 × 10 - 3 100 - 0 × 10 - 6 = 50 A V = β R C R B = 50 × 60 200 = 15
