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}}
