Using Vitamin K (Kirchhoff)
Most of us who have twiddled wires for any length of time have stumbled across Kirchhoff’s Laws, either intentionally or by accident. Even if you’ve never heard of Kirchhoff’s Laws by name, you probably have unconsciously used them. Kirchhoff’s Current Law (KCL) and Kirchhoff’s Voltage Law (KVL) pretty much amount to self-evident truths, a fact that tends to hide their profound importance in everything electrical.
Stated in its most simplistic form, KCL tells us that all the current flowing into a node (a junction between two or more components) must equal all the current flowing out of the node. This can be translated into plumbing terms by saying that the)
