Kirchhoff's circuit laws

“

- [Instructor] Resistors don't have to be combined in just series or in parallel. Electronic components can be combined in both series and parallel to create some pretty complicated looking circuits. For example, this circuit consists of two sets of parallel resistors which are in series with each other. To analyze a network of components like this one, we use two handy equalities known as Kirchhoff's Circuit Laws, which describe how voltage and current are conserved throughout a circuit. Kirchhoff's first law on current is used to understand how the incoming and outgoing currents relate to each other at a circuit node, which is the junction where two or more components meet. You can think of a circuit node as the intersection between roadways and the current traveling through the components are cars traveling along the roads. Since we're not creating or destroying electrons with our circuits, we're just moving them…
