the attractive or repulsive force between two electrically charged objects
Electrostatic Force
100
Doses not transfer a charge on contact
Insulator
100
Electric current that only flows in one direction
Direct Current (DC)
100
Two things that are needed for an electric current to flow
1. Closed circuit
2. Source of electrical energy
100
Make this by wrapping a copper wire around a nail or bolt and attach the ends of the wire to a battery
Electromagnet
200
Likes charges do this
Repel
200
May transfer some charge on contact
Semiconductor
200
Electric current that changes direction periodically
Alternating Current (AC)
200
Electrons only have one path to flow through; one part goes out everything goes out
Series Circuit
200
Copper wire surrounded by magnets when spun really fast turns mechanical energy into electrically energy
Generator

Attract
300
Transfers a charge on contact
Conductor
300
Rate of flow of electric charge past a point or region
Electric Current
300
Multiple paths for the current to flow through; one goes out the others might not go out

Explain the process of how you get electricity in your home. Give as much detail as possible starting with how the power plant generates electricity to how it ends up in your home.
1. A resources uses steam to move a turbine
2. The turbine spins a generator
3. The generator with its copper wire and magnets when spun creates an electrical charge
4. That charge is then sent to a transformer that turns up the voltage
5. It is then carried over long distances by transmission lines
6. Enters into a substation or neighborhood transformer where the voltage is turned back down
7. Distribution line carries the electricity to the house where another transformer may turn the voltage down again before it enters the house
