Electricity is not only used to turn on lights, or make things work, it's also being used in automobiles and other motor-run things. Electric motors also conserve energy and isn't as harmful as a diesel engine or motor engine. Electric motors date back all the way in the 1800's when Thomas Davenport built the first real working electric motor. He used a spinning wheel technique and levers that move back and forth repeatedly. His work ended up being used to move trolleys, but not till 50 years after his death. The picture on the right is an example on how his electric motor looked like. This was used to transport thousands of people each day to work, cities, stores, ect.

AC and DC are the two most common motors. You might know AC motors, because they're used to run our air condition in our homes. DC motors came first, and they have certain advantages and disadvantages that AC motors don't have. Both these motors might be different, but they both use electromagnetic fields. AC motors use a primary and secondary welding. The primary part is attached to the wall power and gets energized, while the secondary motors receive energy from the primary motor. The picture on the left is an example of an AC motor, and how it works.
Electric motors have six main parts; commutator, armature, field magnet, brushes, axle, and a DC, or direct current, of some sort. Each part does something special to make an electric motor to work. A commutator reverses the current direction between the rotor and external circuit. The armature takes the position of a nail in an electric motor. If you look at the image to the left, that is an armature. It’s made by coiling wires around two or sometimes even more poles of metal. The armature a...

...it reaches a strong torque level once the rotor is running quick. One disadvantage is that its slow to start, which means there is low torque when it does start. It's used in fans, appliances, can openers, and it needs above 123 watts to work.

So, in conclusion, electricity is also used in motors, not just light bulbs. Electric motors have been just added into cars to make them more sufficient! Electric motors are becoming more and more popular and also better to use. It's come a long way and has paid off all its work it has done. It's been used to get you from place to place, and provide energy for your household appliances. You probably wouldn't have the nice air conditioning in the summer time if the electric motor was never invented. It has served a purpose and still does today; it has made millions and millions of peoples' lives so much easier.

Essay on Comparing Compact Fluorescent Light Bulbs And Incandescent Bulbs

- Completed Work Task 1: Compare compact fluorescent light bulbs to incandescent light bulbs. In order to begin our research, we first had to prove that our current light bulbs are not the cheapest and not the most efficient choice to light up our buildings. Otherwise, it would have been useless for us to continue. We began our research using government documents, electronic books, and websites that compare incandescent light bulbs to other types of light bulbs.

Light Bulbs : Illuminating The Difficulties Of Attempts At Environmental Protection

- Light Bulbs: Illuminating the Difficulties of Attempts at Environmental Protection Modern conveniences have come a long way in the last few centuries; mankind has invented everything from steam locomotives to computers and the internet, but no creation has been quite so monumental as the light bulb. As recently as the mid-1800s, people still relied on inconveniences like candles and oil lamps for light, and as technology advanced, scientists and engineers recognized that it was time for a change; after his great success with the phonograph, Thomas Edison was eager to rise to this new challenge, beating out his competition to patent the first incandescent bulb in 1879....   [tags: Incandescent light bulb, Fluorescent lamp]

History of Electricity Essay

- The oldest civilization known to understand electricity was the ancient Greeks because of the electric fish in the Nile River. In the 1600’s William Gilbert an English Physician studied electricity and magnetism; studies were continued by other researchers such as Robert Boyle and Benjamin Franklin. Then by the 1800’s scientist Allesandro Volta had identified a way to harness electricity in a battery format and he had also discovered the chemical reactions that electricity could produce. Volta also invented the first device with a steady current known as the electric battery, and he also created the first transmission of electricity by linking positively-charged and negatively-charged connec...   [tags: electricity, science]

The Three Different Types of Household Light Bulbs Essay

- ... The disadvantages of using incandescent globes for lighting are: that they generate too much heat, they are expensive to use, they have to be replaced frequently, and they aren’t energy efficient. The filament in an incandescent light bulb can reach up to 2500 degrees, and the bulb itself can get to 500 degrees. Incandescent bulbs use a lot of electricity and are expensive to run; 50,000 hours of use (including bulbs) costs $352.50 compared to $89.75 (CFL) and $85.75 (LED). Incandescent lights have to be changed regularly as they run for only 1,200 hours compared to the CFL (10,000) and LED (50,000)....   [tags: LED, CFL, energy efficient, durable]

It's Time for the U.S. Government to Phase Out Incandescent Light Bulbs Essay

- The government should phase out incandescent lighting due to the advantages of the new alternatives. At this time, compact fluorescent lights (CFLs) are the central focus of this change and will be used as the example. First, CFLs on the market have better lighting quality than in previous years compared to incandescent bulbs. While quality is not the primary focus of the change, it signals a higher development and readiness for application to the greater public. Popular Mechanics, back in May 2007, designed a study comparing an incandescent light to seven different CFLs....   [tags: environment, alternative energy, lighting]
