The sensitivity of a potentiometer can be Increased by _.
Correct answer: C. increasing the length of the potentiometer wire
- A. Increasing the e.m.f. of the primary coil
- B. Increasing the Potential gradient
- C. increasing the length of the potentiometer wire
- D. Decreasing the length of the potentiometer wire
Explanation
The sensitivity of a potentiometer can be increased by increasing the length of the potentiometer wire.The sensitivity of a potentiometer refers to the change in output voltage per unit length of the potentiometer wire. The increased length of the potentiometer wire allows for finer adjustment of the output voltage. It increases the resolution or sensitivity of the potentiometer, enabling more precise control or measurement of the voltage.

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.
