Wheatstone Bridge

The video tutorial explains how to measure an unknown resistance using a Wheatstone bridge. It describes the components involved, including known and unknown resistances, and the conditions for a balanced bridge where no current flows through the galvanometer. The tutorial covers the application of junction and loop rules to derive the balance condition, which is crucial for determining unknown resistance. By adjusting the variable resistance until the galvanometer shows no deflection, the unknown resistance can be calculated using the balance condition formula.
