Circuit and Network

Have you ever flipped a light switch and nothing happened, even though everything seemed fine? You might have encountered an open circuit or a short circuit—two crucial concepts in understanding any electrical circuit. In this article on the Tech4Ultra Electrical website, I’ll walk you through the key differences between them, using real-world examples and practical insights I’ve

When I first stumbled upon Graph Theory, it was through a tangled mess of electrical wires on my workbench. I had no idea that those chaotic lines had anything to do with math. But then I discovered that every circuit I was building was secretly a graph—nodes connected by edges. That’s when everything clicked. In
