Electricity

Electric Charges Electric charges are much like magnets; opposites attract and like charges repel each other. Two positive charges repel Two negative charges repel One positive and one negative attract

Electric Force There is also an electric field which is similar to a magnetic field The electric field is the area around a charged object in which that particular charge is applied to the objects around it This does not change the fact that if you have multiple charges in a space, opposites will attract and like charges will repel

Static Electricity When an object has a build up of electrons on one side of it and that causes the protons of the object it touches to cling to that object Example: If you rub a balloon on your hair, then your hair will stick to the balloon. (It will also stick to the wall)

Transferring a Charge There are many different ways to transfer a charge, which basically means that the electrons are being transferred. Ways of transferring include: Friction Conduction Induction

Friction When two objects are rubbed together it creates friction This is why if someone drags their feet when they walk then touch a metal door handle they gets shocked. The electrons are being transferred to the persons feet from the floor

Conduction This is when electrons are transferred just by touching an object that has been charged So this is when the electrons transfer from your sock and shoe to your foot then up to your hand. There has been no other cause other than that they are all touching

Induction This is when the charges in the item that you are getting ready to touch are re-arranged so that the opposite charges are ready to bind to those on the other object. This is the actually the touching of the door knob and the shock that occurs.
