Four students discuss how to assign algebraic signs to potential differences while analysing circuits. Consider each of their statements.
(a) Evaluate statement I. Indicate whether it is correct, partially correct, or incorrect, and provide a clear justification.
(b) Evaluate statement II in the same manner as part (a).
(c) Evaluate statement III in the same manner as part (a).
(d) Evaluate statement IV in the same manner as part (a).
(e) Using your evaluations from parts (a)–(d), formulate a concise criterion that guarantees the algebraic sum of potential differences around any closed loop is zero. Support your criterion with reasoning.
