alleryStart learning →The loop rule specifies that the potential around any closed circuit path must be:
AExactly zero
BAt a maximum
CNegative
DTwice as big
Answer & Solution
Correct answer: A. Exactly zero
1. The loop rule is a statement about a full circuit loop.
2. Energy conservation is discussed in terms of the loop rule.
3. The rule specifies that the potential around any closed circuit path must be zero.
4. Rises and drops around the loop must cancel.
