Wheatstone Bridge Variable Resistor
Defined simply a wheatstone bridge is an electric circuit that is used to measure the electrical resistance of a circuit. In our tutorial about resistors in series we saw that each resistor within the series chain produces an ir drop or voltage drop across itself as a consequence of the current flowing through it as defined by ohms law. Module 2 Wheatstone Bridge Part 1 Principles And Basic Applications Ohm S Law Verification And Wheatstone Bridge When balanced the wheatstone bridge can be analysed simply as two series strings in parallel. Wheatstone bridge variable resistor . A wheatstone bridge is an electrical circuit used to measure an unknown electrical resistance by balancing two legs of a bridge circuit one leg of which includes the unknown componentthe primary benefit of the circuit is its ability to provide extremely accurate measurements in contras
