Configuration

A circuit with 3 resistors connected like a T

If Voltage of R₂ is V then

$V=V_{2}{\frac {R_{1}}{R_{1}+R_{3}}}=V_{1}{\frac {R_{1}}{R_{2}+R_{1}}}$

${\frac {V_{2}}{V_{1}}}=({\frac {R_{1}+R_{3}}{R_{1}}})({\frac {R_{1}}{R_{2}+R_{3}}})$

${\frac {V_{2}}{V_{1}}}={\frac {R_{3}+R_{1}}{R_{2}+R_{1}}}$
