# How To Find Equivalent Resistance In A Circular Circuit

By | January 16, 2023

If you're an electrical engineer, one of the fundamental skills you must be familiar with is how to calculate the equivalent resistance of a circuit. Understanding this concept will allow you to design better circuits and build more efficient systems. Calculating equivalent resistance may seem intimidating at first, but it's actually quite simple.

Let's start with a basic example: finding the equivalent resistance in a circular circuit. In this type of circuit, the current will flow from one point to another along the same path, looping around in a circle. To begin, you'll need to identify the resistors in the circuit and measure the resistance in each one. Once you have the individual resistances, you can use Ohm's law to calculate the total resistance.

The key concept behind calculating the equivalent resistance in a circular circuit is known as the “star-delta” transformation. Instead of adding the resistances together, you need to subtract them. This is because the current flowing through the circuit is alternating between two points, and when you subtract the resistances, you end up with the net resistance of the circuit.

To make things easier, you can use a software-based calculator that will calculate the equivalent resistance automatically. You'll just need to enter the individual resistances into the calculator and it will return the net resistance. This can be a great time-saver if you're dealing with more complex circuits.

No matter which method you choose, once you understand the basics of how to calculate equivalent resistance in a circular circuit, you'll be able to easily design and analyze circuits of any complexity. Having a good grasp of this skill will open up countless possibilities for designing electrical systems.

So if you're ready to jump into the world of electrical engineering, learning how to calculate equivalent resistance in a circular circuit is a great place to start. With a little practice, you'll soon be able to confidently design, analyze, and troubleshoot circuits of any size.
