Electrical Loads
Electrical Loads
A load is devise that uses electrical energy. Loads can convert electricity into mechanical, thermal, radiant, or magnetic energy. Every complete circuit needs to include a load.
Motors - a machine powered by electricity or internal combustion, that supplies motive power for a vehicle or for some other device with moving parts. Both A.C. and D.C. motors serve the same function of converting electrical energy into mechanical energy. AC motors are power by an alternating current. DC motors are powered by direct currents. http://en.wikipedia.org/wiki/Electric_motor
Lights - An electric light is a device that produces visible light by the flow of electric current. It is the most common form of artificial lighting and is essential to modern society, providing interior lighting for buildings and exterior light for evening and nighttime activities. http://en.wikipedia.org/wiki/Electric_light
Heaters - a heating element converts electricity into heat through the process of resistive or Joule heating
-What it dose is heat your house and keep it warm from the outside world.
-The way it work is it burns gas and the burn gas goes around and heats places.
-It is important because many homes companies and store use them to keep warm in the winter and keep cold in the summer
-Its is used to heat or keep places cold
-In 1905, Albert Marsh had invented something to heat there places for the cold
Electromagnets - An electromagnet is a type of magnet that has a magnetic field created by an electrical current. A common form of an electromagnet is an insulating wire wrapped around a ferrous metal/material. The first electromagnet was created in 1824 by a British scientist named William Sturgeon. The electromagnet is used for all kinds of purposes always in places where a basic magnet isn't good enough. It works because a wire has a magnetic field so when you coil wire side by side in a sort of tube it amplifies the magnetic field to the size of all the magnetic fields put together. Some electromagnets have a core this can increase the strength of the magnet because it has something to hold onto. The more electricity given to an electromagnet the stronger the magnet will be. http://en.wikipedia.org/wiki/Electromagnet
Speakers - a device that lets you listen on T.V, radio, computer, ETC... Speakers come in vary types you can have a plug in or a wireless speaker, have one that is loud that you can hear from a far distance or have one that you can hear in your house. A speaker is used for sound to raise a volume of a device up to hear it at a louder volume. Alexander Graham Bell patented his first electric loudspeaker (capable of reproducing intelligible speech) as part of his telephone in 1876, which was followed in 1877 by an improved version from Ernst Siemens.

Pumps - A pump is a device that moves liquid or gases by mechanical action. Pumps are used to get fluids or gases moved from one place to another. Pumps work by some mechanism typically reciprocating or rotary, and take energy to do mechanical work by moving the liquid. Pumps are important because they help us get water or other fluids one place to another and they help us get natural resources out of the ground. Pumps are used for moving liquids or gases. The Egyptians were the ones who invented the pump in 2000 BC. http://en.wikipedia.org/wiki/Pump
Solenoids - The term Solenoid was created by French physicist André-Marie Ampère. A solenoid is a coil wound into a tightly packed helix. A solenoid can be either an electromagnet or an inductor, depending on the purpose. A solenoid is an electromagnet when the purpose is to generate a controlled magnetic field. A solenoid is an inductor when the purpose is to impede charges in the electrical current. http://en.wikipedia.org/wiki/Solenoid
Compressors - Gas compressors make a gas pressurized but reducing its volume. There are two different types of compressors: dynamic and positive displacement. Dynamic gas compressors include centrifugal -- which use an impeller to force the gas towards the rim of the impeller -- and axial compressors which use an array of fan like rotters to compress air. Reciprocating compressors use pistons attached to a crankshaft, like an engine block in a car. Scroll compressors are compressors that use two spiraling veins to compress fluids. They are much smaller, reliable, and quieter than other compressors. In total there are 10 different types of compressors; two are dynamic, and the other eight are positive displacement (with the subgroups rotary and reciprocating). http://en.wikipedia.org/wiki/Gas_compressor
