The total resistance of a parallel circuit is 50 Ω. If the total current is 120 mA, the current through the 270 Ω that makes up part of the parallel circuit is approximately_______________?
Correct answer: A. 22 mA
- A. 22 mA
- B. 120 mA
- C. 220 mA
- D. 50 mA
Explanation
The parallel network voltage is V = I_total R_total = 0.12 × 50 = 6 V. Thus the 270 Ω branch current is 6/270 ≈ 22 mA.
