In this post, we will delve deeper into the concepts of series and parallel circuits. Series circuits are those where the components are connected in a single loop, whereas parallel circuits have multiple paths for the current to flow. Understanding the differences between these two types of circuits is crucial in analyzing and designing electrical systems.

Let's start with series circuits. In a series circuit, the total resistance is the sum of the individual resistances. If we have resistors R1, R2, and R3 connected in series, the total resistance, Rt, is given by the formula: Rt = R1 + R2 + R3.

Now, let's move on to parallel circuits. In a parallel circuit, the total resistance is inversely proportional to the sum of the reciprocals of the individual resistances. If we have resistors R1, R2, and R3 connected in parallel, the total resistance, Rt, is given by the formula: 1/Rt = 1/R1 + 1/R2 + 1/R3.

It's important to note that the total voltage across components in series remains constant, while in parallel circuits, the voltage across each component is the same.
