Which law states that the total current entering a junction in an electrical circuit is equal to the total current leaving the junction?

A. Ohm's Law
B. Kirchhoff's Current Law✓ Correct Answer
C. Kirchhoff's Voltage Law
D. Joule's Law of Heating

💡 Solution & Explanation

Kirchhoff's Current Law is derived from the principle of conservation of electric charge, asserting that the algebraic sum of all electric currents meeting at any electrical junction must equal zero. Other principles such as Ohm's Law define the direct proportionality between voltage and current across a conductor under constant physical conditions.
