| A | B |
|---|
| friction | rubbing two things together creates a charge and heat |
| atoms | tiny particles that make up matter |
| nucleus | core of atom where protons and neutrons are |
| batteries | portable sources of electricity formed by chemical reaction |
| protons | sub-atomic positively charged particles found in the nucleus |
| amps | amount of electricity running through the circuit |
| resistance | force opposing the electric current that makes friction |
| voltage | amount of force pushing electricity through a current |
| conduction | movement of electricity through actual contact |
| induction | electrical charge produced without direct contact |
| circuit | closed continuous path the electric current travel |
| electricity | energy that comes in two forms, static and current |
| electric current | flow of electrons through a circuit |
| photovoltaic cells | convert light energy to electricity |
| static electricity | charges that build and stay in one place until discharged |
| insulators | matter the prevents or greatly restrict flow of electricity |
| repel | like charges do this |
| attract | opposite charges do this |
| conductors | material that lets electricity travel with little resisitance |
| charge | the electric force of protons and electrons, having an unequal amount of this produces it |
| resistors | slow or limit electric current, but still let it pass through |
| electrons | sub-atomic negatively charged particle that orbit the nucleus of an atom and make up electricity |
| switch | device to open and close circuits |
