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