What is the total resistance of a voltmeter on the 10 V range when the meter movement is rated for 50 µA of full-scale current ?
Correct answer: C. 200 kO
- A. 10 kO
- B. 20 kO
- C. 200 kO
- D. None of the above
Explanation
The total voltmeter resistance is R = V/I = 10/(50 × 10^-6) = 200,000 ohms, or 200 kΩ. Hence option c is correct.
