What does Kirchhoff's Voltage Law state for any closed loop in a circuit?
AThe total current in the loop is constant at every point.
BThe sum of all resistances in the loop is zero.
CThe algebraic sum of all potential differences around a closed loop is zero.
DThe potential difference across each component is identical.
Answer & Solution
Correct answer: C. The algebraic sum of all potential differences around a closed loop is zero.
Kirchhoff's Voltage Law states that when you move around a complete loop, voltage rises and drops cancel algebraically. Thus, the net sum of potential differences is zero.
