Electricity - MNES4

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.
