Combien de millihenrys égalent 10 000 microhenrys?
- A100 millihenrys
- B1 millihenry
- C1 000 millihenrys
- D10 millihenrys
Correct answer: D — 10 millihenrys. Question tirée de la banque officielle d'ISDE.
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.
