Kirchhoff Multi-loopHardQuestion 31677

Question

In a loop with EMF₁ = 10 V, R₁ = 2 Ω, EMF₂ = 4 V (opposing), R₂ = 2 Ω: current (assuming EMF₁ drives clockwise) is:
  1. A
    3.5 A
  2. B
    1.5 A
    Correct
  3. C
    7 A
  4. D
    5 A

Correct answer

1.5 A

Explanation

Net EMF = 10 − 4 = 6 V. Total resistance = 2 + 2 = 4 Ω. I = 6/4 = 1.5 A (clockwise).
