Energy Systems

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).

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...

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.
