2. Static electricity Introduction Static electricity is all about charges which are not free to move. This cause them to build up in one place and it often ends with a spark or a shock when they do finally move. Only electrons moves. +ve or –ve are always produced by movement of electrons. There are insulators and conductors. From conductor passes from insulators no.

3. Uses of static electricity Painting produces an even coat is to give the surface being painted a static charge and the paint the opposite charge. To remove pollutants from smoke. Thunderclouds have huge amounts of electrostatic charge which cause electrical polarization in the objects around. strikes. when the attraction of the ground ant the cloud over comes lightning strikes.

4. STATIC ELECTRICITY Electrical charge hat is fixed in a position in some materials.Electrical charge hat is fixed in a position in some materials. This consists the charge in motions.This consists the charge in motions. Two different types of electrical charges that are positive and negative charge.Two different types of electrical charges that are positive and negative charge. They exert forces on each other. Like Electric Charges Repel Unlike Charges Attract. In every day life electrical charges consists of an axcess of an axcess of particles called electrons.In every day life electrical charges consists of an axcess of an axcess of particles called electrons. Conductors are able to separate their electrons from their atoms and move.Conductors are able to separate their electrons from their atoms and move.

5. GENERAL KNOWLAGE When two insulators are rubbed electrons will be scabbed off one and dumped on the other.When two insulators are rubbed electrons will be scabbed off one and dumped on the other. Finally one will be positively charged and the other negatively charged.Finally one will be positively charged and the other negatively charged. Moving electrons by rubbing is called friction.Moving electrons by rubbing is called friction. Charging by friction also takes place when a person walks on nylon. An electroscope is used to detect electricity.Charging by friction also takes place when a person walks on nylon. An electroscope is used to detect electricity. The way the electrons move depends on the material.The way the electrons move depends on the material. The example is this:The example is this:

6. Charging by induction is a bit tricky. It tends to induce Charge when something that is not charge moves near something that is charged.It tends to induce Charge when something that is not charge moves near something that is charged. This is because electrons in the uncharged object moves towards or against.This is because electrons in the uncharged object moves towards or against. The result is always the same. The new arrangement of the charge makes the two objects pull together.The result is always the same. The new arrangement of the charge makes the two objects pull together. This is because the repelling charge are now further apart than the attraction charge.This is because the repelling charge are now further apart than the attraction charge.

7. A charge builds up, so does the voltage. The greater the charge on an insulator the greater the voltage between it and the earth.The greater the charge on an insulator the greater the voltage between it and the earth. If the voltage is big enough there will be a spark..If the voltage is big enough there will be a spark.. High voltage cables can be dangerous for this reason.High voltage cables can be dangerous for this reason. Big sparks have been known to leap from overhead cables to earth.Big sparks have been known to leap from overhead cables to earth. A charged conductor can be discharged safely by connecting it to earth with a metal strip.A charged conductor can be discharged safely by connecting it to earth with a metal strip.

When synthetic clothes are dragged over each other electrons get s dragged off, leaving static charges on it, this leads to a inevitable attractionWhen synthetic clothes are dragged over each other electrons get s dragged off, leaving static charges on it, this leads to a inevitable attraction Other some general features
