# How To Find Total Resistance In Series And Parallel Circuit

By | September 22, 2023

When it comes to understanding electric circuits, one important concept to grasp is the total resistance in series and parallel circuits. While it may seem daunting at first, once you understand the basics, you'll be able to apply this knowledge to a variety of situations. In this article, we'll break down the key components of calculating total resistance and provide some tips on how to make the process easier.

First, let's define what we mean by series and parallel circuits. In a series circuit, the components are connected in a single loop, meaning that the current flows through each component in a sequential manner. On the other hand, in a parallel circuit, the components are connected in multiple branches, meaning that the current splits and flows through each branch simultaneously. Now, let's dive into how to calculate total resistance in each type of circuit.

In a series circuit, the total resistance is simply the sum of the individual resistances. So if you have three components with resistances of 10Ω, 20Ω, and 30Ω, the total resistance would be 60Ω. However, in a parallel circuit, the calculation is a bit more complex. The total resistance is actually less than the smallest individual resistance. To find the total resistance, you need to use the formula 1/Rtotal = 1/R1 + 1/R2 + 1/R3...and so on. So if we take the same example as before, the total resistance in a parallel circuit would be 6Ω. This is because the current has multiple paths to flow through, making it easier for it to pass through the circuit.

Understanding total resistance in series and parallel circuits is crucial for troubleshooting and building electrical systems. By following these simple calculations, you can ensure that your circuits are functioning properly and efficiently. So next time you're faced with a series or parallel circuit, remember these tips to easily find the total resistance.
