The sensitivity of a voltmeter which uses a 100 µA meter movement is ____________?
Correct answer: B. 10 kO/V
- A. 1 kO/V
- B. 10 kO/V
- C. 5 kO/V
- D. Data insufficient
Explanation
Voltmeter sensitivity is the reciprocal of full-scale deflection current: 1/(100 microampere) = 10,000 ohms per volt, or 10 kΩ/V. A smaller movement current gives a higher ohms-per-volt sensitivity.
