Intro to Electricity
What IS Electricity?
A form of energy resulting from the existence of charged particles
How do we harness this ENERGY?
Conductor Something that allows electricity to flow Examples; metal Water air
Insulator something that does NOT let electricity flow Examples Glass Plastic Rubber Porcelain
Power Source Something that supplies electricity Examples; Battery Generator solar panel
Battery Portable power source that has a positive and negative. The negative has extra electrons. They want to move to the positive side
Circuit path for electricity to flow
Load Something that uses electricity Example Toaster Ipod Dvd player
Short Circuit unwanted contact of wires or parts in a circuit resulting in damage or malfunction of the circuit Example: two bare wires touching
Voltage, Resistance & Current
Voltage (V) The “push” of electricity in a circuit Measured in VOLTS (V)
Resistance (R) The resistance to flow of electricity Measured in OHMS (Ω)
Current (I) The rate of flow of electricity in a circuit Measured in AMPHERES (A)
