Electricity - MNES4
| Question | Answer |
|---|---|
| electricity | The interactions of electric charges. |
| electric current | A continuous flow of negative charges(electrons). |
| circuit | The pathway taken by an electric current. |
| static electricity | The buildup of electrical charge on a material. |
| lightning | A discharge of static electricity in the atmosphere. |
| open circuit | Like an open bridge, it does not allow electricity to flow. |
| closed circuit | Like a closed bridge, it allows electricity to flow. |
| series circuit | Has only one path. If one light goes out, they all go out. |
| parallel circuit | Has more than one pathway. If one light goes out, the other circuit light stays on. |
| conductors | An object that allows electricity to pass through, such as metal. |
| insulators | An object that DOES NOT allow electricity to pass, such as rubber, plastic, and wood. |
| electromagnetic | A non-permanent magnet created by wrapping a wire around certain iron. |
| magnetic poles | The stronger point of a magnet (usually north and south). |
| magnetic field | A region of magnetic force around a magnet. |
| dry cell | A battery that changes chemical energy into electrical energy. |
| repel | Like charges repel, push away. South and South/North and North. |
| attract | Opposite charges attract. North and South. |
| electrical energy | related to the movement of charged particles. |
| electrical energy | It can come from batteries or from power plants. It is sent through wires to homes and businesses. |
| current electricity | the electricity that flows through a circuit, a moving electrical charge |
| circuit | the path that electricity can move through |
| generator | a device that creates alternating current by spinning an electric coil between the poles of a powerful magnet. |
| switch | a device that controls the current in a circuit; it can open or close an electric circuit |
| positive | an electrical charge represented by + (plus sign) |
| negative | an electrical charge represented by a - (minus sign). |
| opposite charges | charges that attract each other |
| like charges | charges that repel each other |
| dry cell | a battery that changes chemical energy into electrical energy |
| electromagnet | a temporary magnet created when current flows through wire wrapped in coils around an iron bar |
| permanent magnet | a magnet that keeps and does not loose magnetism |
| temporary magnet | a magnet that eventually looses magnetism |
| Benny Franklin | Proved lightning was a form of electricity by using a key, wet string, and a kite. |
| Benny Boy Franklin | Discovered lightning rods help protect buildings and ships from damage. |
| Mikey Faraday | Discovered electromagnetic induction, the electric motor, the transformer, and the generator. Maybe chewing gum too. |
| Tommy Edison | Invented the light bulb and built the first power plant. Thank goodness because now I can find the bathroom at night thanks to both. |
