According to Kirchhoff's Voltage Law, the algebraic sum of all potential differences around a closed loop is
Aequal to the total current in the loop
Balways positive
Czero
Dequal to the resistance of the loop
Answer & Solution
Correct answer: C. zero
Kirchhoff's Voltage Law states that the algebraic sum of all emfs and voltage drops around any closed loop is zero. This expresses conservation of energy in circuits.
