A transistor connected at common-emitter mode contains load resistance of `5 k Omega` and an input resistance of 1 k Omega` . If the input peak voltage is 5 mV and the current gain is 50, find the voltage gain :

Options

A. ` 250 `
B. ` 500`
C. ` 125`
D. ` 50`

Answer

A

Explanation

Voltage gain ` = (R_(" out " ) )/(R_(" in ")) xx beta`
` " " = (5)/(1) xx 50`
` " " = 250 `
