When an electrical current flows through a wire, the current generates a small magnetic field around the wire. If the wire is shaped into a coil, the magnetic field becomes much stronger, thus an inductor is created. Today we’re going to dive into the world of inductors and see how these amazing devices shape the…
What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric. Initially…
