The Kirchhoff’s Law Calculator helps analyze electrical circuits using the two fundamental principles of Kirchhoff’s Current Law (KCL) and Kirchhoff’s Voltage Law (KVL). KCL states that the total current entering a junction equals the total current leaving it, ensuring the conservation of electric charge. KVL asserts that the algebraic sum of all voltages around any closed loop in a circuit is zero, confirming the conservation of energy. By selecting either KCL or KVL mode and entering current or voltage values, this calculator instantly checks whether the circuit satisfies Kirchhoff’s laws. It is widely used in electrical engineering, physics, and circuit design to verify current distribution and voltage consistency across complex networks.
