------------------------------------------------- Electric generator In electricity generation‚ an electric generator is a device that converts mechanical energy to electrical energy. A generator forces electric charge (usually carried by electrons) to flow through an external electrical circuit. It is analogous to a water pump‚ which causes water to flow (but does not create water). The source of mechanical energy may be a reciprocating or turbine steam engine‚ water falling

Andre‚ a socially mobile 2010 graduate of Wellborn University‚ has been enjoying a successful software sales career in New York City. When I arrived‚ I stepped out of my car for Andre to help me park (raised in Arizona‚ my parallel parking skills are null). He happily greeted me as he took my keys and moved my driver’s seat all the way back. Being well over 6’ tall‚ he towered over me. On our way to his apartment building he expressed his excitement for my association with Lori before directing me

set‚ “Polly Pocket TM” which contained small magnets. These magnets‚ if extracted from the toys‚ could be swallowed by children. If more than one magnet is swallowed‚ then it is possible that the two would be attracted to each other in the child’s stomach‚ causing the child’s intestines to rupture or tear. In August‚ 2007‚ Mattel reported over 400 cases of the magnets coming loose. Three serious injuries occurred where children swallowed the magnets and needed surgery. Barbie TM dolls also affected

Purpose: The purpose of this experiment was to calculate the mass of composition of each component in a mixture containing sand‚ salt and iron filings. Introduction: Many substances that we use on a daily basis are in fact part of a mixture. A scientist separated a mixture to obtain the specific substance that was in need. Many of the compounds and mixtures today are not found in its pure form‚ but in mixtures. Many scientists have the impression that separating mixtures is an important part of

Stepper Motor Introduction A stepper motor is an electromechanical device which converts electrical pulses into discrete mechanical movements. It divides a full rotation into a number of equal steps. A stepping motor is driven by a series of electrical pulses‚ which are generated by the MCU in an NC system. Each pulse causes the motor to rotate a fraction of one revolution‚ called the step angle. The possible step angles must be consistent with the following relationship: ∝=360ns Where α = step

The first speaker ever created was known as the dynamic loudspeaker. It was created in the 1920’s by Edward Kellogg and Chester Rice. The loudspeaker produces a magnetic field which then causes a coil or magnet to move. The coil or magnet is connected to the diaphragm. There are more speakers than just the horn‚ such as‚ such as‚ electrodynamic loudspeaker‚ flat panel - planar‚ electrostatic‚ multi-cell diaphragm and piezoelectric. Speakers are used to produce sound. Sound is an energy which is
