Question A-003-006-005

Voltmeter sensitivity is usually expressed in ohms per volt. This means that a voltmeter with a sensitivity of 20 kilohms per volt would be a:

Correct Answer

50 microampere meter

Explanation

Sensitivity (ohms/volt) = 1 / Full-scale current (amperes). So, Full-scale current = 1 / (ohms/volt) = 1 / (20,000 Ω/V) = 0.00005 A = 50 microamperes.
