Lead Acid Battery

source url Lead Acid Battery There are two types current namely ac and dc. We know that, DC current can be stored. The electrical energy in dc nature store in the form of chemical energy. The device that stores electrical energy in chemical energy is called “electric cell“. Electric cell has small storage capacity. So cells are connected […]

Insulating Materials

Insulating Materials Insulating materials are the materials that is able to insulate. It prevent the current flows through them. The materials that posses insulating properties is called an insulator. In this article, we will study about classification, Properties, applications of insulating materials. Classification of insulating Materials Insulating Materials are divided into three types Solid insulating […]

Introduction to Electrical Machines

Electrical Machines  Electrical Machines are the machines that required electrical energy for their operation. These machines may be ac or dc (means what kind of supply requires for their operation). The ac machines are two types static and rotating machines. On the other hand dc machines are only rotating one. In this article we will […]
