A three-branch parallel circuit carries a total current of 1.2 mA . If I₁=0.2 mA and I₂=0.7 mA , then what is the value of I₃ ? A) 2.4 mA B) 8.7 mA C) 7.2 mA D) 0.3 mA

Question

Quizplus · Accepted Answer

In a parallel circuit, the total current is equal to the sum of the currents in each branch. Therefore, 1.2 mA = 0.2 mA + 0.7 mA + I₃ Solving for I₃, we get: I₃ = 1.2 mA - 0.2 mA - 0.7 mA = 0.3 mA Therefore, the answer is D.
