Question

The transfer characteristic curve of a transistor, having input and output resistance 100 Ω and 100 k Ω respectively, is shown in the figure. The voltage and power gain, are respectively:, 5 × 10 4 , 2.5 × 10 6, 2.5 × 10 4 , 2.5 × 10 6, 5 × 10 4 , 5 × 10 6, 5 × 10 4 , 5 × 10 5

MARKS App · Accepted Answer

Current gain β = Δ I C Δ I B = 5 × 10 - 3 100 × 10 - 6 = 50 Voltage gain ( A V ) = β R o u t R i n = 50 × 100 × 10 3 100 = 5 × 10 4 Power gain = A V × β = 50 × 5 × 10 4 = 2.5 × 10 6
