The electric overhaul of society obviously brought many fresh new dangers with it‚ but it eliminated some of the old ones‚ like the naked flames of gas lighting that was commonly used in homes and factories then. The Joule heating effect that can be found in light bulbs is also present in electric heating. Electric heating has been thought of as wasteful in the past because in order to create that heat energy

1 ELECTRIC MOTORS I. Introduction Electric motors are considered to be important mechanical devices. They usually convert the electrical energy coming from the mechanical device into its kinetic energy to make it work (Petingco and Resurreccion‚ 2011). In this exercise‚ the students were tasked to use an example of an electric motor‚ identify its parts‚ and make it work. All electrical motors are equipped with stator and rotor. Stator is known as the stationary part of an electric motor

The effects of electric force can be summarized as the law of electric charge: Pieces of matter with the same kind of charge repel

is to use the electric motor instead of gasoline one. An electric car is a car that powered by an electric motor rather than a regular gasoline engine. There are several major differences between gasoline and electric cars. First of all‚ “the electric motor will replace the gasoline engine” (“How Electric”‚ 2004). Secondly‚ “the electric motor is powered by a controller” (“How Electric”‚ 2004). Thirdly‚ “the controller gets power from the rechargeable batteries” (“How Electric”‚ 2004). In

1 Introduction The word system is derived from the Greek word "Systema" which means an or- ganized relationship among functioning units or components. System analysis is a structured approach to problem solving that breaks down a system into its compo- nent pieces to determine how these component work together by interacting with each other to achieve their purpose. Descartes emphasised that a problem under consideration should be divided into as many parts as possible and then examined
