Q:

When is the bridge circuit balanced?

A) When voltage is applied B) When current flows through the opposite ends of the bridge circuit
C) When no current flows through the galvanometer D) When impedance is minimum
 
Answer & Explanation Answer: C) When no current flows through the galvanometer

Explanation: The bridge circuit is said to be balanced when no current flows through the null indicator which is generally a galvanometer.
