1) In a common emitter transistor amplifier β = 60, R0 = 5000 Ω and internal resistance of a transistor is 500 Ω. The voltage amplification of amplifier will be A) 500 B) 460 C) 600 D) 560 Answer: Option CExplanation:Voltage amplification $A_{v} = \beta\frac{R_{0}}{R_{i}}$ = $60\times\frac{5000}{500}$ = 600
