Question: If the galvanometer in a Wheatstone bridge has a high resistance, what is the effect on the sensitivity of the bridge?

Options:

Correct Answer: Increases sensitivity

Solution:

A high resistance in the galvanometer increases the sensitivity of the bridge.

If the galvanometer in a Wheatstone bridge has a high resistance, what is the effect on the sensitivity of the bridge?

If the galvanometer in a Wheatstone bridge has a high resistance, what is the effect on the sensitivity of the bridge?

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 what a galvanometer is. It is a device that detects and measures small electric currents.
Step 3: Recognize that the resistance of the galvanometer affects how easily it can detect small changes in current.
Step 4: Realize that a high resistance in the galvanometer means it will draw less current from the circuit.
Step 5: Understand that with less current drawn, the galvanometer can detect smaller differences in current more easily.
Step 6: Conclude that a high resistance in the galvanometer increases the sensitivity of the Wheatstone bridge, allowing it to detect smaller changes in resistance.

Sensitivity of Wheatstone Bridge – The sensitivity of a Wheatstone bridge refers to its ability to detect small changes in resistance. A higher resistance in the galvanometer allows for smaller current flow, making it easier to detect minute changes in the balance of the bridge.
