What is the loop rule?
Understand the Problem
The question is asking about the loop rule, which is a principle in circuit analysis stating that the sum of the potential differences (voltage) in any closed loop in a circuit must be zero. This concept is based on the conservation of energy.
Answer
Kirchhoff's loop rule states that the sum of potential differences around any closed loop must equal zero.
Kirchhoff's loop rule states that the algebraic sum of potential differences, including voltages supplied by voltage sources and resistive elements, around any closed loop must equal zero.
Answer for screen readers
Kirchhoff's loop rule states that the algebraic sum of potential differences, including voltages supplied by voltage sources and resistive elements, around any closed loop must equal zero.
More Information
Kirchhoff's loop rule is also known as Kirchhoff's voltage law. It's essential for analyzing complex circuits, ensuring the conservation of energy within the circuit loops.
Tips
A common mistake is forgetting to account for the polarity of voltage drops and gains when applying the loop rule; it's important to maintain consistency in the sign convention.
