AIPMT PRELIMS 2009 Physics Kirchhoff's Laws MCQ Question
See the electric circuit shown in this Figure. Which of the following equations is a correct equation for it?
ε₂ - i₂r₂ - ε₁ - i₁r₁ = 0
-ε₂ - (i₁ + i₂)R + i₂r₂ = 0
ε₁ - (i₁ + i₂)R + i₁r₁ = 0
ε₁ - (i₁ + i₂)R - i₁r₁ = 0
Correct Answer
Detailed Explanation
Using Kirchhoff's loop rule, the sum of the potential differences around any closed loop in a circuit must equal zero. Option C correctly applies this rule to the given circuit.
