Static ElectricityStatic Electricity

This is an electrical This is an electrical charge that builds up on charge that builds up on a materiala material

Static electricity is Static electricity is present on some present on some materials such as your materials such as your hair, or a comb.hair, or a comb.

These charges can build These charges can build up and cause a up and cause a discharge, causing a discharge, causing a shock, especially when it shock, especially when it is cold outside.is cold outside.

Before Static Before Static DischargeDischarge

A negatively A negatively charged object, charged object, (my hand) is (my hand) is attracted to attracted to the positively the positively charged object charged object (the door (the door knob).knob).

During During DischargeDischargeWhen the two When the two

objects come objects come into contact, the into contact, the oppositely oppositely charged objects charged objects exchange exchange particles and a particles and a shock is shock is produced.produced.

After DischargeAfter Discharge

After the discharge the two objects After the discharge the two objects return to their original neutral return to their original neutral state.state.

Conductors and InsulatorsConductors and Insulators

Conductors are materials that Conductors are materials that negatively charged particles flow negatively charged particles flow through easily.through easily.

An example of negatively charged An example of negatively charged particles would be an electrical particles would be an electrical current.current.

Examples of some conductors are Examples of some conductors are silver, gold, copper, and watersilver, gold, copper, and water

CircuitsCircuits

A circuit is the pathway that an A circuit is the pathway that an electrical current follows.electrical current follows.

The three items needed for an The three items needed for an electrical circuit are a light bulb, wire electrical circuit are a light bulb, wire and a battery.and a battery.

Types of CircuitsTypes of Circuits

There are three types of circuits:There are three types of circuits:

Open or incomplete circuitOpen or incomplete circuit Closed or complete circuitClosed or complete circuit Switch circuit which can be complete Switch circuit which can be complete

or incompleteor incomplete

Incomplete CircuitIncomplete Circuit

An incomplete, or An incomplete, or open circuit, has a open circuit, has a gap which does not gap which does not allow the electricity allow the electricity to flow through the to flow through the wire from the wire from the battery and light battery and light the bulb.the bulb.

Complete CircuitComplete Circuit

A complete circuit is A complete circuit is one in which there one in which there are no gaps. In this are no gaps. In this kind of circuit kind of circuit electricity flows electricity flows without stopping without stopping through the wire through the wire from the battery to from the battery to the light bulb and the light bulb and lights it up.lights it up.

COMPLETE CIRCUIT

Switch CircuitSwitch Circuit A switch circuit A switch circuit

contains, in contains, in addition to three addition to three items needed for items needed for the other two the other two circuits, a switch circuits, a switch that can be opened that can be opened to stop the to stop the electrical flow or electrical flow or closed to allow the closed to allow the electricity to flow electricity to flow and light the bulb.and light the bulb.

SWITCH CIRCUIT

Two Types of Switch CircuitsTwo Types of Switch Circuits

There are two types of switch circuits:There are two types of switch circuits: Series circuit – in this kind the parts Series circuit – in this kind the parts

are connected so that the electric are connected so that the electric current passes through each part one current passes through each part one after another along a single pathwayafter another along a single pathway

Parallel Circuit – in this type the Parallel Circuit – in this type the current passes along more than one current passes along more than one pathwaypathway

Bar Magnets and Bar Magnets and ElectromagnetsElectromagnets

There are two main There are two main types of magnets that types of magnets that are used by people BAR are used by people BAR MAGNETS and MAGNETS and ELECTROMAGNETS.ELECTROMAGNETS.

Information on magnetsInformation on magnets

A magnet is an object that attracts iron A magnet is an object that attracts iron and other certain metals.and other certain metals.

The force of a magnet is stronger at two The force of a magnet is stronger at two areas called the magnetic polesareas called the magnetic poles

ElectromagnetsElectromagnets

Electromagnets are Electromagnets are strong temporary strong temporary magnets that are magnets that are created by created by electricity running electricity running through a wire or through a wire or other conductor.other conductor.

ElectromagnetsElectromagnets

Electromagnets Electromagnets attract objects that attract objects that are made of iron.are made of iron.

The advantage to The advantage to this kind of magnet this kind of magnet is that it can be is that it can be turned on and off.turned on and off.

Electromagnets Electromagnets have no poles.have no poles.

Bar magnets are permanent Bar magnets are permanent magnets. This means that they keep magnets. This means that they keep their magnetism for a long time.their magnetism for a long time.

The earth is like a bar magnet The earth is like a bar magnet because it has two magnetic poles.because it has two magnetic poles.

Bar MagnetsBar Magnets

Bar magnets have Bar magnets have two unlike poles, two unlike poles, their force of their force of magnetism is magnetism is stronger at each stronger at each pole.pole.

Unlike poles attract Unlike poles attract one another, and one another, and like poles repel one like poles repel one another.another.
