Question

if the feedback fraction of an amplifier is 0.01,then voltage gain with negative feedback is approximately....​

Answer 1

so if you talk about negative feedback which is also known as degenerative feedback which decreases the value of voltage gain A. Such as it is given as

$a = v0 \div vi + mv0$

or

$a \: {new} = a \div 1 + \beta a$

where the term

$\beta a \: is \: known \: as \: feedback \: fraction$
