Bridge Circuit Formula. The four arms or branches of the bridge circuit are formed by the resistances r 1 to r 4. From the standard bridge rectifier circuit vi is the input voltage.

The resistance of balanced wheatstone bridge between a and c is p q r s p q r s p q r s p q r s. The potential at point b is calculated similarly except we use r2 and r4. Vb is the diode voltage rd is the dynamic resistance r is the load resistance vo is the output voltage.
V o v m sinωt.
The sensitivity of bridge depends upon value of resistances. Therefore the voltage ratios can be written as. And the thevenin resistance rth. In this case 25 v x 800 w 1000 w 800 w 11 11 v.
