How many millivolts equal two volts?
- A 2 000 mV
- B 0.000 002 mV
- C 2 000 000 mV
- D 0.002 mV
Correct answer: A — 2 000 mV. From the official ISED question bank, verified word for word.
Why
Two volts equal 2 000 millivolts because the prefix "milli" means one thousandth, so you must multiply the number of volts by 1 000 to find the equivalent in millivolts. The full explanation — and one for every question — is in Pro.
