What is loop rule?
Understand the Problem
The question is asking for an explanation of the loop rule, which is a concept in physics related to electrical circuits and Kirchhoff's laws. Specifically, it pertains to the principle stating that the sum of the potential differences (voltage) around any closed loop in a circuit must equal zero.
Answer
The algebraic sum of potential differences in any loop must be zero.
The algebraic sum of potential differences in any loop must be equal to zero.
Answer for screen readers
The algebraic sum of potential differences in any loop must be equal to zero.
More Information
Kirchhoff's Loop Rule is based on the conservation of energy, asserting that energy is neither created nor destroyed within an electrical loop.
Tips
Common mistakes include not accounting for the correct sign (positive or negative) of voltage drops or gains.
