NEET Physics Kirchhoff's Laws MCQ Question
In a circuit diagram with multiple loops, which of the following correctly describes Kirchhoff's Loop Rule?
The algebraic sum of potential differences in any closed loop is zero.
The total current entering a junction equals the total current leaving it.
The sum of emfs in a loop equals the sum of voltage drops only if resistances are equal.
The product of current and voltage is conserved across a junction.
Correct Answer
Detailed Explanation
According to Kirchhoff's Loop Rule, the algebraic sum of potential differences around any closed loop in a circuit must be zero, ensuring energy conservation.
