In a Wheatstone bridge, if the galvanometer shows a current, which of the following statements is true?
Correct Answer: Bridge is unbalanced
- Step 1: Understand what a Wheatstone bridge is. It is a circuit used to measure unknown resistances by balancing two legs of a bridge circuit.
- Step 2: Know that a galvanometer is an instrument used to detect and measure small currents in the circuit.
- Step 3: Recognize that in a balanced Wheatstone bridge, there is no current flowing through the galvanometer.
- Step 4: If the galvanometer shows a current, it means that the two sides of the bridge are not equal in resistance.
- Step 5: Conclude that the presence of current in the galvanometer indicates that the Wheatstone bridge is unbalanced.
