NEET Physics Resistance & Resistivity MCQ Question
What does the loop rule state regarding the algebraic sum of changes in potential around any closed loop?
It is equal to zero.
It is equal to the total current.
It is dependent on the resistors used.
It is the sum of the voltages across each resistor.
Correct Answer
Detailed Explanation
The loop rule states that the algebraic sum of changes in potential around any closed loop involving resistors and cells is zero, indicating that when returning to the starting point, the total change in electric potential must be zero.
