Light bulb

Resistance

Of a material measures how well electricity can move through it

Conductor

Of electricity ia a material that allows electricity to flow through it freely. Metals.

Non conductor or insulator

A material that resists the flow of electricity and does not allow electrons to pass through it. Have great resistance

Iron

A metal that is a poor conductor

Most metals

Are good conductors of electricity

Circuit

Electricity flows from negative side of battery through the wires and lights the bulb,the electricity continues to travel around to the positive side of the battery.

Current electricity

Electricity that flows through wires. The path it follows is called a circuit

Electrical curcuit

Flow of energy from a source and back to the source. When circuit is open energy does not flow . When the circuit is closed the energy dies flow

Light bulb

Gives off heat and light

Copper

Good conductor. Commonly used in electrical circuits

Filament

In a light bulb a very thin piece of wire that resisted the flow of electricity with in it. It becomes so hot that it glows. The thinner filament will have a brighter bulb because there is more resistance

Solder

Points of metal on the base and the side of the insulator which allow electric current to flow into the bulb

Batteries

Store chemical energy. Made up of positive and negative terminal which is called polarity. Both - & + terminals must be used for there to be a flow of electricity.

Static electricity

When two surfaces touch one another each has a different charge. Rub together

Insulators -examples of

Wood, glass, plastics, good insulators have high resistance.plastic around wires and bulb holders are insulators.
