For measurement of potential difference, potentiometer is preferred in comparison to voltmeter because
- A potentiometer is more sensitive than voltmeter
- B the resistance of potentiometer is less than voltmeter
- C potentiometer is cheaper than voltmeter
- D potentiometer does not take current from the circuit
Answer & Solution
