Torque Equation For DC Motor

Torque Equation for DC Motor Torque is a rotational force that helps for rotating the armature of DC motor. Torque is produced by electromagnetic effect. In simple words we can say that, when a conductor carrying current placed in a magnetic field or flux a mechanical force experienced by the conductors and conductor moves in […]

Lead Acid Battery

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 […]

Superposition Theorem

Superposition Theorem This theorem is useful for those circuits that contain two or more than two sources. This theorem is applicable only when network or circuit contains with linear elements. The sources of emf connected only in parallel not in series. According to this theorem the current flowing through any section is the algebraic sum […]

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 […]
