| electricity | the energy of moving electric charges |
| electron | particle with a negative charge |
| proton | particle with a positive charge |
| neutral atom | contains equal number of protons and electrons |
| Law of Conservation of Charge | electric charges cannot be created or destroyed |
| static electricity | the buildup of electric charges |
| current electricity | the flowing of electric charges that require a power source |
| circuit | path that electricity travels along |
| parts of a circuit | power source, load, conductor |
| Law of Electric Charges | like charges repel, unlike charges attract |
| power source | part of the circuit that supplies the energy; battery, generator |
| load | part of the circuit that does the work; light, motor, radio |
| conductor | material that allows electricity to travel through it; metal |
| insulator | material that does not allow electricity to travel through it; plastic, rubber |
| series circuit | circuit with only 1 path for electricity to travel along |
| parallel circuit | circuit with more than one path for electricity to travel along |
| Ohm's Law | describes the relationship between resistance, voltage, and current; resistance equals voltage divided by current |
| resitance | electrical friction; the opposition to the movement of electrical charges flowing through a material |
| factors that effect resistance | temperature, length, thickness of a wire |
| magnetism | the force of attraction between magnetic materials |
| magnetic field | the region around a magnet where magnetic forces are exerted |
| poles | the ends of a magnet; where magnetic force is strongest |
| iron, cobalt, nickel | magnetic materials |
| Law of Magnetic Attraction | like poles repel, unlike poles attract |
| magnetic domain | in a magnetic substance, domains are aligned |
| induction | an object becomes magnetic, or charged just by coming near a magnetic or charged substance |
