Current I₁, I₂ and I₃ meet at a junction (node) in a circuit. All currents are marked as entering the node. If I₁ = – 6 sin (ω t) mA and I₂ = 8 cos (ω t) mA, then I 3 will be

1. 10 cos (ωt + 36.87) mA
2. 14 cos (ωt + 36.87) mA
3. – 14 sin (ωt + 36.87) mA
4. 10 cos (ωt + 36.87) mA

Correct Option: D
