If there are a total of 120 mA into a parallel circuit consisting of three branches, and two of the branch currents are 40 mA and 10 mA, the third branch current is_________________?
Correct answer: B. 70 mA
- A. 50 mA
- B. 70 mA
- C. 120 mA
- D. 40 mA
Explanation
The branch currents in a parallel circuit add to the total current. The missing branch is 120 − 40 − 10 = 70 mA.
