In this tutorial about transformers I will explain the basics in simple terms. As we know transformers can work without any moving parts inside and it is mainly used to change voltage levels so that we can transfer energy from one circuit to another through electromagnetic induction. We use alternating current (AC) in our homes […]

Understanding Electrical Energy and Power, with Calculations
Just think about turning on a light switch and the entire room is filled with light. That is how electrical energy can work its magic. It is that which provides the impetus for many activities in our everyday existence. But what exactly is it? Electrical energy is not only the ability to light up a […]
Quantities and Units in Electrical Circuits
Electrical quantities are expressed using the conventional electrical units (volt, ampere, ohm) and their prefixes. Prefixes are used when the amounts being measured are too big or small to be represented in a suitable way using only the basic units. Fundamental Electrical Units: The standard electrical units for voltage, current, and resistance are the volt […]
