In a negative feedback amplifier ,the gain without feedback is 100,feed back ratio is 1/25 and input voltage is 50 m V.Calculate.
i)gain with feedback
ii)feedback factor
iii)output voltage
iv)feedback voltage
v)new input voltage so that output voltage with feedbck the output voltage without feedback

Explanation

gain with feedback
`A_f= (A )/( 1 + beta A ) = (100 )/(1 + 1//25 xx 100 ) = 20`
