Si dix résistances de même valeur "R" sont raccordées en parallèle, quelle formule stipule la résistance de l'ensemble?
- AR / 10
- B10 / R
- C10 x R
- D10 + R
Correct answer: A — R / 10. Question tirée de la banque officielle d'ISDE.
Why
When ten identical resistors are connected in parallel, the electricity has ten separate paths to flow through, making it much easier for current to pass than through a single resistor. The full explanation — and one for every question — is in Pro.
