Wheatstone Bridge

व्हीटस्टोन सेतु

In Class 12 Physics, this topic from Chapter 3: Current Electricity explains how a Wheatstone Bridge compares electrical resistances accurately. Students study its four-arm arrangement, the role of the galvanometer as a null detector, and the balance condition under which no current flows through the galvanometer. They apply the relation between the four resistances to determine an unknown resistance and understand how the principle supports practical measurement methods such as the meter bridge.
