According to Kirchhoff's Voltage Law, what is the algebraic sum of all potential rises and drops around any closed loop?
AEqual to the total current in the loop
BEqual to zero
CEqual to the total resistance in the loop
DAlways positive
Answer & Solution
Correct answer: B. Equal to zero
Kirchhoff's Voltage Law says that when all emfs and voltage drops are added with sign, the net result around a complete loop is zero.
