The potentiometer is mainly not used- Correct Answer To determine the value of high capacitance

CONCEPT:

  • Potentiometer: A potentiometer is a three-terminal resistor in which the resistance is manually varied to control the flow of electric current.

  • A potentiometer is used to compare the voltage of two or more primary cells.
  • A potentiometer is used to determine the internal resistance of the primary cell.
  • A potentiometer is used to determine the high resistance of the circuit.
  • A potentiometer is used to determine the emf of the cell.
  • A potentiometer is used to compare potential differences across two resistors.

EXPLANATION:

  • A potentiometer is used to determine the large resistance, not capacitance.
  • A potentiometer is used to find the EMF of the cell and compare the EMF of the cell.
So option 3 is correct.
