What does Kirchhoff's Voltage Law state for any closed loop in a circuit?
AThe product of current and resistance is constant everywhere.
BThe current entering a loop equals the current leaving it.
CThe algebraic sum of all potential rises and drops around the loop is zero.
DThe sum of all resistances around the loop is zero.
Answer & Solution
Correct answer: C. The algebraic sum of all potential rises and drops around the loop is zero.
Kirchhoff's Voltage Law expresses conservation of energy in a circuit loop. As you go around a complete loop, the total of all voltage rises and drops must add to zero.
