  1. Kirchhoff’s junction rule is a reflection of (B) conservation of charge. It states that the total current entering a junction equals the total current leaving, ensuring no charge accumulation. This follows from the principle that charge cannot be created or destroyed at a junction, making conservation of charge the fundamental basis of this rule.
