Three 47 Ω resistors are connected in parallel across a 110 volt source. The current drawn from the source is approximately_______________?
Correct answer: D. 7.06 A
- A. 2.3 A
- B. 780 mA
- C. 47 mA
- D. 7.06 A
Explanation
Three identical 47 Ω branches in parallel have an equivalent resistance of 47/3 ≈ 15.7 Ω. The source current is therefore 110/15.7 ≈ 7.06 A.
