On which of the following voltage range settings will a voltmeter present the minimum load on a circuit?
Correct answer: D. 1,000 VCompare Power Rates
- A. 1 V
- B. 50 V
- C. 500 V
- D. 1,000 VCompare Power Rates
Explanation
A voltmeter's input resistance is generally highest on its highest voltage range, so it draws the least current from the circuit. The 1,000 V range therefore produces the minimum loading.
