Laws of electronics: KCL
This post describes one of the basic laws of circuit analysis, more precisely KCL (Kirchhoff’s Current Law), which states that the the sum of the currents leaving and entering a node is zero. KCL Kirchhoff's Current Law states that the the sum of the currents leaving and entering a node is zero. We need to take into …
