Energy

Power and energy are two main terms used in electrical and electronic systems. Many people think that energy and power are the same concepts. These two terms are related but not the same. Energy is basically the ability to do work. Power is the amount of energy used per unit...

The unused power caused by the inductive and capacitive effects of transmission lines or electrical loads using alternating current is called reactive power. Reactive power, also known as virtual power or phantom power, is measured by VAR (Volt-ampere reactive).

Photometry is the measurement of visible light as perceived by the human eye. Photometry is a name formed by combining the words photo and metry. Photo is a prefix meaning light. Metry refers to the process of measurement.

Electrical devices can consume energy even when we are not using them, causing our electricity bill to be high. So what are the effective ways that we can easily apply to reduce the electricity bill?

When you heat something, you notice that its temperature rises. This may make you think that heat and temperature are the same thing. Because of this misconception, heat and temperature are often used interchangeably. Although the two concepts are related, they are not the same. It is therefore very important...

LED lighting devices experience significant energy loss during AC-DC power conversion, electro-optical conversion (electroluminescence), and wavelength conversion. Unlike conventional technologies, in LEDs, all energy losses in the light emitting process are expelled as heat. This presents a major engineering challenge where more than half of the power input is converted...

Light consists of small packets of energy called photons. Light energy is a form of electromagnetic radiation and is the only form of energy visible to the human eye. Light energy travels in waves and is very fast. The sun, stars, lamps, lasers, and hot objects are examples of light...

Capacitors and supercapacitors are passive components that store energy in the form of an electrostatic field. Although the function of both is to store energy, there are some important differences between them. Supercapacitors can store more charge than regular capacitors and provide energy much faster than a battery.

The Light + Building took place between October 2-6 this year, and the new calendar is 3-8 March 2024. It would be correct to say that this year was not good as the previous ones, as the number of exhibitors and visitors is much lower than last years.

Kinetic energy is the energy possessed by an object in motion. Potential energy, on the other hand, is the energy that an object has because of its position or state. This is the main difference between kinetic energy and potential energy.

Founded in 1971, the company Metalogalva – Irmãos Silvas S.A. is the oldest company of the VigentGroup. This industrial...

A smart plug is a smart home device that plugs into a traditional electrical outlet and lets you control anything plugged into it via the app or virtual assistant. The smart plug makes even ordinary non-smart devices a part of the smart home network. It makes it possible to control...

Lighting Master Plan (LMP) is a crucial discipline describing the main aspects of urban lighting in a city. By this source, it is possible to control and renew or improve the lighting system, which reveals the identity of the city.

Energy or particles emitted from a source and moving in the air are called radiation. Radio waves, microwaves, X-rays and gamma rays are types of electromagnetic radiation. Visible light is also a kind of electromagnetic radiation. However, this constitutes only a small part of the electromagnetic spectrum.
