Question:
The resistance can be measured most accurately by:
The resistance can be measured most accurately by:
Show Hint
For precise resistance measurement, especially in labs, always prefer the bridge method over voltmeter-ammeter or multimeters.

- Voltmeter-ammeter method
- Bridge method
- Multi-meter
- Megger
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Among all methods listed, the bridge method (like Wheatstone Bridge or Kelvin’s Double Bridge) provides the most accurate measurement of resistance.
It works on the principle of null deflection, eliminating errors due to the resistance of connecting wires and contact resistance.
The voltmeter-ammeter method is less accurate due to the influence of meter internal resistances.
Multimeters are convenient but not as precise, especially at very low or high resistance values.
Meggers are primarily used for high insulation resistance and not precise resistance measurements.
