Question

Quizplus · Accepted Answer

The difference between a balanced and an unbalanced Wheatstone bridge is a small current, which can be detected using a sensitive galvanometer. An ammeter measures current, not the difference between balanced and unbalanced, a voltmeter measures voltage not the difference between balanced and unbalanced, and an ohmmeter measures resistance, not the difference between balanced and unbalanced.
