How to Solve Complicated Circuits with Kirchhoff's Current Law (KCL)?

Kirchhoff’s Current Law (KCL) explained in 1 minute. KCL was first introduced in 1847 by the German physicist Gustav Robert Kirchhoff, and it is a direct consequence of the law of conservation of charge. KCL states that the algebraic sum of all the currents at any node in a circuit equals zero. In other words, the sum of the currents entering a node must be equal to the sum of currents leaving that node. Coupled with Ohm’s Law, Kirchhoff’s laws (KCL and KVL) allow us to solve most electric circu
