In the figure, the values of currents I₁, I₂ and I₃ respectively are

Options

  1. A6 A, 1.5 A and 1 A
  2. B4 A, 2.5 A and 2 A
  3. C4 A, 2.5 A and 1 A
  4. D6 A, 4.5 A and 1.5 A

Correct answer

C. 4 A, 2.5 A and 1 A

Step-by-step solution

Applying Kirchhoff's Current Law (KCL) at the first junction, the total current entering the junction must equal the total current leaving it: 5 = 1 + I₁ I₁ = 5 - 1 = 4 A Applying KCL at the second junction: I₁ = 1.5 + I₂ 4 = 1.5 + I₂ I₂ = 4 - 1.5 = 2.5 A Applying KCL at the third junction: I₂ = 1.5 + I₃ 2.5 = 1.5 + I₃ I₃ = 2.5 - 1.5 = 1 A Therefore, the values of I₁, I₂ and I₃ are 4 A , 2.5 A and 1 A respectively. Answer: 4 A, 2.5 A and 1 A
