For measuring a very high resistance we should use_______________?
Correct answer: C. Meggar
- A. Kelvin's double bridge
- B. Wheat stone bridge
- C. Meggar
- D. None of the above
Explanation
A Megger, or insulation-resistance tester, is designed to measure very high resistances by applying a comparatively high test voltage. Kelvin’s double bridge is used for very low resistance, while a Wheatstone bridge is suited to moderate resistance values.
