Bridge Circuit Calculator. Calculate the total series and parallel resistance of a circuit using digikey s parallel and series resistor calculator. The wheatstone bridge is an electrical bridge circuit used to measure resistance.
How to use the calculator decide your calculation parameters. Figure 4 the thevenin equivalent circuit of the bridge circuit with r 5 restored. Bridge circuits rely on sensitive null voltage meters to compare two voltages for equality.
The wheatstone bridge is an electrical bridge circuit used to measure resistance.
Bridge circuits rely on sensitive null voltage meters to compare two voltages for equality. Wheatstone bridge calculator the wheatstone bridge is a very useful circuit. When used with operational amplifiers the wheatstone bridge circuit can be used to measure and amplify small changes in resistance r x due for example to changes in light intensity as we have seen above. The wheatstone bridge network consists of four resistors r a r b r c and r x interconnected.
