How many millihenries equal 10 000 microhenries?
- A 1 millihenry
- B 1000 millihenries
- C 10 millihenries
- D 100 millihenries
Correct answer: C — 10 millihenries. From the official ISED question bank, verified word for word.
Why
Ten millihenries is correct because a millihenry is one thousand times larger than a microhenry, so you simply divide the 10 000 microhenries by 1 000 to get 10. The full explanation — and one for every question — is in Pro.
