If a multimeter has a sensitivity of 1000 O per volt and reads 50 V full scale, its internal resistance is _____________?
Correct answer: B. 50 kO
- A. 20 kO
- B. 50 kO
- C. 10 kO
- D. None of the above
Explanation
Internal resistance equals sensitivity multiplied by the full-scale voltage: 1000 Ω/V × 50 V = 50,000 Ω = 50 kΩ. Therefore the full-scale meter resistance is 50 kΩ.
