The circuit which gives continuously varying potential is called:
Correct answer: C. Potential divider
- A. Complex network
- B. Wheatstone bridge
- C. Potential divider
- D. All of the above options are correct
Explanation
A potential divider, also known as a voltage divider, is a circuit arrangement composed of resistive elements connected in series. It is designed to divide a voltage into smaller fractions across different points of the circuit. By adjusting the values of the resistors, the output voltage at the junction between the resistors can be continuously varied. This configuration indeed provides continuously varying potential.

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.
