Figure shows currents in different parts of electrical circuit. The value of current ' i ' is
Options
- A3.1 A
- B3.4 A
- C3.6 A
- D6.3 A
Correct answer
A. 3.1 A
Step-by-step solution
Applying Kirchhoff's Current Law to the left junction, the sum of entering currents equals the sum of leaving currents. Two 4 A currents enter, while current I₁ leaves, giving 4 + 4 = I₁ so I₁ = 8 A . At the right junction, I₁ enters while 2 A , 2.6 A , and i leave. Thus I₁ = 2 + 2.6 + i . Substituting I₁ = 8 yields 8 = 4.6 + i , so i = 3.4 A . Final answer: 3.4 A
