An non$-$inverting amplifier uses two resistors with $5$ percent tolerance and values $R_F=33k$ as the feedback resistor and $R_S=1\mathrm{.}2k$ as the source resistor of an operational amplifier.

Question $1$

What is the formula to find the closed$-$loop voltage gain of this amplifier?

$A_V=-\frac{R_F}{R_S}$

$A_V=1+\frac{R_F}{R_S}$

$A_V=1-\frac{R_F}{R_S}$

$A_V=1+\frac{R_S}{R_F}$

$A_V=\frac{R_F}{R_S}$

$A_V=\frac{R_S}{R_F}$

$A_V=1-\frac{R_S}{R_P}$

$A_V=-\frac{R_S}{R_F}$
