Joseph's Sci Final
Static Electricity and Current Electricity
| Question | Answer |
|---|---|
| matter | made up of atoms, anything that has mass and takes up space |
| atoms | tiny particles with no charge (equal positive and negative charge) |
| positive | electrical charge (+) |
| negative | electrical charge (-) |
| attract | come close together, opposite charges |
| repel | push away, same charges |
| neutral | no charge |
| humidity | wetness in the air |
| static electricity | the buildup of electrical charge |
| jump | when charge builds up so much it goes from the cloud to the ground |
| discharge | the movement of static electricity into an object, ZAP! |
| conductors | material that electricity flows through easily (metal, water) |
| insulators | material that electricity doesn't flow through easily (wood, air, rubber) |
| lightning | a huge discharge of static electricity from a cloud |
| circuit | path that electricity flows through |
| current electricity | electricity that flows through a circuit |
| closed circuit | a path with no holes, electricity can flow through it |
| open circuit | a path with holes, electricity cannot flow through it |
| switch | tool that can make a circuit open or closed |
| amperes | the measure of how many electrons flow past a place in a circuit |
| resistor | allows electrical energy to turn into heat or light |
| short circuit | a side circuit with low resistance, accidentally made |
| dry cell | changes chemical energy into electrical energy |
| wet cell | has electrodes, changes chemical energy into electrical energy |
| electrodes | negative and positive terminals of a wet cell |
| series circuit | many objects next to each other on a circuit, electricity is shared |
| parallel circuit | each object has its own circuit, electricity has 2 paths to travel through |
| fuse | has a piece of metal that will heat up and melt and make an open circuit |
| circuit breakers | switch that will make an open circuit when electricity flows through it |
