What is kVA?

kVA stands for kilo volt-amperes. It is basically the unit of apparent power and is the product of RMS values of voltage and current. One kVA is 1000 volt – amperes Apparent power Apparent power is the actual amount of power drawn from the source. It includes both true power and reactive power. Apparent power … Read more

Electrical wiring color codes – Important

Electrical engineers and electricians follow predefined wiring color codes while wiring houses, commercial buildings and industrial panel boards. It is mandatory to know the electrical wiring color codes before attempting any kind of repair works yourself. The electrical wiring color codes followed is slightly different in every part of the world depending on the standards … Read more

Electric Short Circuit

Electricity is required for lighting up our homes and powering up the industries. It can be constructive or destructive depending on how carefully it is handled. One of the most dangerous situations is when there is a short circuit. You may have heard of fired accidents caused due to short circuits or even deaths due … Read more

Real, Reactive, Complex and Apparent power

Today most of the electric loads work on AC power. Every electric load possess a certain amount of resistance. Some loads, in addition to resistance, possess capacitance or inductance. The total impedance offered by the load to the current flow determines how much active and reactive power it would consume. The concepts of active power, … Read more

Basics of Alternating current

Electrical Power is the basis of modern life. It forms the basis for industrial and infrastructure developments and makes our life more comfortable. This article will help you understand the basics of Alternating current. Today, most of the power we use is generated and transmitted as alternating current. Discovery of alternating current has made power … Read more

Conductance | What is conductance?

Every material in the universe is believed to be made up of atoms. In an atom, electrons are bound to its nucleus by a strong force of attraction by the protons in the nuclei. In some materials few free electrons are available. These electrons can move freely along the material. Such materials with free electrons … Read more

Capacitance| What is a capacitor?

The device that offers pure capacitance is known as a capacitor. A capacitor is a two-terminal energy storage device, that stores energy in its electric field. It can be found in turning and filtering circuits. It consists of two metallic plates facing each other and separated by a dielectric medium such as air, ceramic, mica … Read more

Inductance | What is an inductor?

Inductance A conductor carrying current produces a magnetic field around it. This magnetic field follows a circular path. When the same conductor is wound over a cylindrical solid core, the magnetic field formed around it amplifies. Any change in the rate of current flow through this conductor causes a change in the magnetic field, thereby … Read more

What is Electric Power?

Before reading about electric power it is essential to have a basic idea about power. The word power is a little tricky to understand. Consider that you are riding a bicycle at a speed of 20km/hr for an hour. A certain amount of work is done by you here. The amount of work done by … Read more

What is energy?

Energy can be defined as the capacity to do work. It can also be defined as “stored work”. The terms energy and power are confusing and are interchanged most of the times. Consider that you are riding a bicycle at a speed of 20km/hr for an hour. A certain amount of work is done by … Read more
