उदाहरण Vout = 0 V — for balance (Vout = 0), Rx would need to be 1 kΩ

उदाहरण Bridge is currently balanced.

Each half is its own divider, and the output is the difference between their midpoints: $V_{आउट} = V_{ex} \times (\frac{R_{2}}{R_{1} + R_{2}} - \frac{R_{x}}{R_{3} + R_{x}})$

The bridge is balanced — $V_{आउट} = 0$ — when $R_{1} \times R_{x} = R_{2} \times R_{3}$ , so an unknown resistance resolves to $R_{x} = \frac{R_{2} \times R_{3}}{R_{1}}$ . That is how strain gauges, load cells and RTDs are read against three known resistors.
