AIPMT MAINS 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 - i₂ r₂ - ε₁ - i₁ r₁ = 0
- ε₂ - (i₁ + i₂) R + i₂ r₂ = 0
ε₁ - (i₁ + i₂) R + i₁ r₁ = 0
ε₁ - (i₁ + i₂) R - i₁ r₁ = 0
Correct Answer
Detailed Explanation
The correct equation is derived from Kirchhoff's loop rule, which states that the sum of the potential differences around any closed loop in a circuit must be zero.
