A CELL OF INTERNAL RESISTANCE 0.01 OHM CAN BE MEASURED ACCURATELY USING THE

  • A. Ohm meter
  • B. metre bridge
  • C. potentiometer ✓
  • D. electroscope

 

The answer to the question is: C. potentiometer

A potentiometer is a device used to measure the potential difference between two points in an electric circuit. It consists of a long wire of uniform cross-section, made of a material with high resistivity, and a sliding contact called a jockey. When the jockey is moved along the wire, the potential difference across its ends can be measured accurately. By adjusting the length of the wire over which the potential difference is measured, the potentiometer can be used to measure very small potential differences with high precision, making it suitable for measuring the internal resistance of a cell.
