20 Δεκ 2008 · Electricity is a controllable and convenient form of energy used in the applications of heat, light and power. This article discusses about the basics of electricity.
Energy is not an object in itself, rather, energy refers to a condition or state of an object. The main types of kinetic energy are: • Electrical Energy—The energy associated with the movement of electrons. When elec-trons flow through wires, we call it electricity.
1 Ιαν 2004 · • There are only two basic kinds of energy: kinetic energy (KE) and potential energy (PE). • Kinetic energy is associated with motion. • Potential energy is associated with interactions...
By the end of this section, you will be able to: Express electrical power in terms of the voltage and the current. Describe the power dissipated by a resistor in an electric circuit. Calculate the energy efficiency and cost effectiveness of appliances and equipment.
Among fossil fuels the chemical composition of the original fuel changes, resulting in by-products of combustion, or emissions. This chapter provides a brief introduction to energy’s importance for human life and economic functioning, and paints a broad picture of the current energy scene.
What is energy? If asked, “Well, what exactly is energy, then?”, a lot of people pussyfoot around. You’ll find answers like: “energy is the ‘go’ of things” “energy is the capacity to do work” “energy is a mathematical quantity that is conserved in an isolated system”
