According to Kirchhoff's junction rule, the sum of currents entering a junction must equal:

A.A) The sum of currents leaving the junction

B.C) The voltage across the junction

C.B) Zero

D.D) The resistance of the junction

Explanation

Core Concept

Kirchhoff's junction rule (also known as Kirchhoff's current law) states that the algebraic sum of currents entering any junction in a circuit must equal the algebraic sum of currents leaving that junction. This is based on the principle of conservation of electric charge.

Correct Answer

AA) The sum of currents leaving the junction
