Electricity Study Guide
- A Closed circuit is one that allows electricity to flow through- there are no gaps or breaks in the electric current; an example would be when you flip the switch in your bedroom and the light comes on.
- An Open circuit is one in which there is a gap somewhere and the electric current cannot flow in a complete path. There could be a wire that is not connected somewhere, keeping the circuit from being complete.
- Static electricity is a type of electricity that is a build up of electrical charges on a surface.
- Positive and negative charges- in our experiment using balloons to create static electricity we discovered that positive charges repel positive charges and negative charges repel negative charges. The only charges that attract are opposite charges.
- Conductors are materials that allow electricity to flow through them.
- Insulators are materials that will NOT allow electricity to pass through them.
- Electromagnets are temporary magnets that are made when a current passes through a wire wrapped around an iron core.
If you haven’t already done so, please memorize these important science terms. The quiz will be coming up this week. Happy Studying!!!!
