In order to achieve accuracy, the slide wire of a potentiometer should be:
Correct answer: A. As long as possible
- A. As long as possible
- B. As short as possible
- C. Neither too small neither too large
- D. Very thick
Explanation
A longer slide wire allows for finer resolution because it increases the overall resistance range available for measurement. With a longer wire, there are more incremental positions along the wire where the voltage can be tapped, providing greater precision. However, longer wires may introduce more resistance and can be more susceptible to noise or interference.hence Option A is the correct answer.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
