<ul><li><p>Electrical EnergyWhere does it come from and where does it go? </p></li><li><p>What is Electrical Energy?Electrical Energy is the energy of electric charges. </p></li><li><p>Where Does Electrical Energy Come From? 4 Basic Areas1. Dry Cell Batteries2. Wet Cell Batteries3. Photocells4. Thermocouples</p></li><li><p>Where Does It Go? Electrical energy can be converted into basically any other type of energy</p></li><li><p>But, Where Does Electricity Come From? From ATOMS!!!!The smallest particle a substance can be broken down into</p></li><li><p>Well, then what part of the atom is the important part???***the negatively charged particles found outside of the nucleus</p></li><li><p>Wellthen how do they move from one object to another?2 Main Culprits </p></li><li><p>ConductorsMaterials that negative charges move easily through </p><p>Charges are free to move around Good conductors: metals such as silver, aluminum, copper, and mercury </p></li><li><p>InsulatorsA material in which negative charges do not move well </p><p>Found on electrical wire to keep you from shocksGood Insulators: Plastic, rubber, glass, wood, and air</p></li><li><p>Charging ObjectsEvery object begins as neutral. Meaning it has no chargewe call this a 0 (zero charge).Then, in some situationsthey can become</p></li><li><p>Charge It!!!Objects become charged because they lose or gain electronsGain = becomes negativeLose = becomes positive</p></li><li><p>Well why do my pants stick to me then, they are insulators right?Right, but also wrong.hmmmThe buildup of electric charges on an objectStatic = does not move</p></li><li><p>Ouchyou shocked me!!!When the static electricity in an object leaves the objectExamples: cracking noise, shock, flash of light</p></li><li><p>Opposites Attract!!!Objects that have opposite charges are attracted to each other</p><p>Result = objects are pulled together</p></li><li><p>Sames Repel!!!Objects that have the same charges are repelled</p><p>Result = objects repel each other</p></li></ul>
