## Wheatstone Bridge Analysis A Wheatstone bridge measures unknown resistance by balancing two divider legs. ### Formula **V_bridge = V_s x [R3/(R1+R3) - R4/(R2+R4)]** Balanced when **R1/R3 = R2/R4** (bridge voltage = 0).
हल किया गया उदाहरण
10 V supply, R1=R3=1k, R2=R4=2k.
- 01Left: R3/(R1+R3) = 1000/2000 = 0.5
- 02Right: R4/(R2+R4) = 2000/4000 = 0.5
- 03V_bridge = 10 x (0.5 - 0.5) = 0 V (balanced)
अक्सर पूछे जाने वाले प्रश्न
What does balanced mean?
Bridge voltage is zero and no current flows through the galvanometer.
What is it used for?
Precision resistance measurement, strain gauges, load cells, and temperature sensors.
Can bridge voltage be negative?
Yes, indicating reversed polarity compared to the assumed direction.
