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:
- A1 milliampere meter
- B50 milliampere meter
- C100 milliampere meter
- D50 microampere meter
Correct answer: D — 50 microampere meter. From the official ISED question bank, verified word for word.
Why
A sensitivity of 20 kilohms per volt means the meter needs 20,000 ohms of resistance for every volt it measures. The full explanation — and one for every question — is in Pro.
