The internal resistance of a 20,000 ohm/volt voltmeter set on its 5 V range is_____________?
Correct answer: B. 100,000 Ω
- A. 20,000 Ω
- B. 100,000 Ω
- C. 200,000 Ω
- D. 1,000,000 Ω
Explanation
Voltmeter resistance equals sensitivity multiplied by the selected range: 20,000 Ω/V × 5 V = 100,000 Ω. This high resistance limits the meter's loading of the measured circuit.
