|---|---|---|---|---|---|
| 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.
🗑
