A DC machine is an electromechanical device that converts electrical energy into mechanical energy, or vice versa, using direct current (DC). It works on the fundamental principle of electromagnetic induction, which was discovered by Michael Faraday. DC machines are classified into two main types: DC generators and DC motors. A DC generator converts mechanical energy … Read more
What is Transmission Line? A transmission line is like a big electric road. Just like trucks carry goods from one city to another, a transmission line carries electricity from power stations to our homes, schools, offices, and factories. Simple Example: Imagine a water pipe. Water flows through the pipe and reaches your tap. In the … Read more
Electrical Power Distribution System The distribution system is the part of the electric supply network that delivers electricity from the distribution substation to the end consumers (homes, shops, farms, etc.). An electrical distribution system is a network of equipment that carries electricity from high-voltage transmission lines to homes, businesses, and other users. It acts as … Read more
Measurement of Power in Three-Phase Systems A wattmeter is a device used to measure the average or real power in AC circuits. While the method for measuring single-phase power is discussed in Chapter 1, this section focuses on the measurement of three-phase power. There are three main methods used for measuring the active (real) power … Read more
ideal Voltage and Current Sources Electricity is a part of our daily life. We use it to light our homes, run our fans, charge our phones, and power our TVs. But have you ever thought — where does this electricity come from? That’s where voltage sources and current sources come in. Let’s understand them in … Read more

Open circuit and short circuit What is an Open Circuit? | An open circuit means there is a break or gap in the path where electricity should flow. Imagine a road where a bridge is broken — cars can’t pass through it. In the same way, when a wire or part of the circuit is … Read more
Introduction to Magnetic Circuits We all know that magnets can pull things like pins or nails. But have you ever wondered how this invisible pull works inside machines like fans, motors, or transformers? Well, it’s all about something called a magnetic circuit. Just like electric current flows in a loop through wires in an electric … Read more
Magnetic Hysteresis When we take a piece of magnetic material—like iron—and magnetise it first in one direction, and then in the opposite direction, something interesting happens. The magnetic strength inside the material does not follow the applied force exactly. Instead, it lags behind. This delay is called Magnetic Hysteresis. 🔄 What is Magnetic Hysteresis? Magnetic … Read more
Magnetic Flux Density Have you ever seen how magnets pull things without touching them? This invisible force spreads out in space like magic. But how do we measure this magnetic power in a certain area? That’s where Magnetic Flux Density comes in. 🌟 What is Magnetic Flux Density? Magnetic Flux Density is a way to … Read more
