Question

What is the condition called when the galvanometer shows zero deflection in a Wheatstone bridge, with \[I_g = 0\]?

पर्याय

• Zero potential condition

• Equilibrium state

• Null condition

• Balance condition

Answer 1

The balance condition is the state of a Wheatstone bridge under which the galvanometer shows zero (null) deflection, meaning no current flows through it (\[I_g = 0\]). At this point, the potentials at the two galvanometer junctions are equal, and the ratio of resistances satisfies a specific mathematical relationship.
