When a loop does not have any voltage source, the algebraic sum of the IR voltage drops alone must total zero.

Question

Quizplus · Accepted Answer

According to Kirchhoff's Voltage Law, the algebraic sum of all voltages in a loop, including both the voltage sources and the voltage drops (IR drops), must equal zero. If there are no voltage sources in the loop, then the sum of the IR voltage drops alone must indeed total zero.

When a Loop Does Not Have Any Voltage Source, the Algebraic
