What is a Solar Power Efficiency? Definition: Solar power efficiency refers to the ratio of the electrical energy produced by a solar panel or system to the amount of sunlight energy that hits the panel’s surface. It is expressed as a percentage and indicates how effectively the panel converts sunlight into usable electricity. Higher efficiency … Read more
What is Electrical Energy Efficiency? Definition: Electrical energy efficiency refers to the ratio of useful output of an electrical system to the input energy supplied to it. It is a measure of how effectively electrical energy is converted into the desired output, whether that output is mechanical work, heat, light, or other forms of useful … Read more
Duke Energy Power Company History: Duke Energy, one of the largest electric power holding companies in the United States, has a rich history that spans over a century. Here’s an overview of its history: Early Beginnings (1900s) 1904: Dr. Walker Gill Wylie and James Buchanan Duke founded the Southern Power Company to provide electricity for … Read more
What is a Volt Ampere? Definition: A Volt-Ampere (VA) is a unit of measurement for apparent power in an electrical circuit. It represents the product of the root-mean-square (RMS) voltage and the RMS current in the circuit. Apparent power combines both real power (which performs actual work and is measured in watts) and reactive power … Read more
What is a Watt Hour? Definition: A watt-hour (Wh) is a unit of energy equivalent to one watt (1 W) of power expended for one hour (1 h) of time. It is commonly used to measure electrical energy consumption. Here’s a breakdown of the concept: Watt (W): A unit of power that measures the rate … Read more
What is Watt and Kilowatt? History of Watt and Kilowatt? The concepts of watt and kilowatt have their roots in the development of the study of energy and power in the 18th and 19th centuries. Watt: James Watt (1736-1819): The watt is named after James Watt, a Scottish engineer and inventor who made significant improvements … Read more
What is a Current Transformer? Definition: A current transformer (CT) is an electrical device used to measure alternating current (AC). It produces a reduced current accurately proportional to the current in the circuit, which can then be safely connected to measuring and recording instruments. CTs are commonly used in power system protection, control, and measurement … Read more
