The collector resistance and the input resistance of a CE amplifier are respectively `10 k Omega and 2 k Omega. If beta` of the transistor is 49, the voltage gain of the amplifier is

Options

A. 125
B. 150
C. 175
D. 245

Explanation

The voltage gain of the ampifier `(A _(v))`
`= beta .(R _(out))/(R _(I n))= 49 xx (10)/(2)`
`= 49 xx 5 = 245 V`
