How to use the calculator. 1. Calculate R4 resistance for a balanced bridge, or. 2. Calculate the cross-bridge voltage V b. To calculate R4, select "Resistance of R4 for balanced bridge" and add the values for R1, R2, and R3 as directed. To calculate the cross-bridge voltage, select "Voltage across the bridge V b " and input the values for R1 ...
Nov 5, 2022 · Our Wheatstone bridge calculator is simple to use: Select what you need to calculate. You can: Calculate the unknown resistance in a balanced Wheatstone bridge, or. Calculate the bridge voltage in an unbalanced Wheatstone bridge. Enter all the known values. In the case of a balanced Wheatstone bridge, you need to enter three resistance values.
As Wheatstone bridge is in balanced condition potential difference across AB is zero. We can consider the middle resistor to be short-circuited. Hence resistance across AB does not contribute to effective resistance. The two resistors R in upper branch are in series. Similarly the two resistors R in lower branch are in series.
The given circuit is equivalent to the unbalanced Wheatstone's bridge, hence, the equivalent resistance is given by (standard result) R e q = 2 G + P + Q 2 P Q + G ( P + Q )
Oct 6, 2014 · Apply an arbitrary voltage across the terminals (say, v ab = 1V) and find i ab. Then, use the formula v ab = v oc - i ab R t and solve for the Thevenin resistance. answered Oct 10, 2014 at 18:19. Justin Bell.
I am trying but could not find any way of calculating the equivalent resistance of this circuit. Please help me. Should I use the Wheatstone Bridge equivalent resistance, the Y-$\\Delta$ transform, ...
