A technician measures 10A using a clamp-on inductive ammeter placed around the battery positive cable on a truck with the ignition on and engine off. He also measures 10A with the inductive ammeter placed around the battery negative cable. Which best explains the reason for these measurements?
A) Kirchhoff's voltage law
B) Ohm's law
C) Kirchhoff's current law
D) The rules of series-parallel circuits

Question

Quizplus · Accepted Answer

Kirchhoff's current law states that the total current entering a junction must equal the total current leaving the junction. In this case, the current measured on the positive cable is equal to the current on the negative cable, as the current flowing into the battery is the same as the current flowing out.
