Two 6 ohm resistors are connected in parallel. Their combined resistance is
- A. 12 ohms
- B. 6 ohms
- C. 3 ohms
- D. 0.33 ohms
Explanation
For two equal resistors in parallel the result is simply half of one of them, so 3 ohms. The general rule is that the reciprocals add, and the total is always smaller than the smallest branch because the current has more than one path available. Adding to get 12 ohms is the series answer.
