Static Electricity

Static Electricity. Summary. Only two types of charge!. Positive Charge (protons – therefore in nuclei of atoms ) Negative Charge (electrons – therefore orbiting atoms – and can be ‘brushed off’ onto other atoms making ions. Only electrons move…. Positive Charged Object – too few electrons

  1. Static Electricity Summary

  2. Only two types of charge! • Positive Charge (protons – therefore in nuclei of atoms ) • Negative Charge (electrons – therefore orbiting atoms – and can be ‘brushed off’ onto other atoms making ions

  3. Only electrons move… • Positive Charged Object – too few electrons • Negative Charged Object – too many electrons • Net charge is ALWAYS due to ELECTRON transfer – protons moving about would change the elements you are dealing with.

  4. Opposite Charges attract

  5. …Like Charges Repel

  6. It all depends on gravity… • Whether you can see a charged object ‘react’ to another one depends on weight. Two forces are in operation – electric force and gravitational force. • If the electric force is bigger the object can be seen defy gravity… or in the case of the object on the left inertia and friction !

  7. Charging by Friction • Some objects are more attractive to electrons than others. If you rub a balloon (very attractive to other atoms’ electrons) together with a woollen jumper. It will ‘steal’ some of the electrons and leave the jumper postive. • The balloon will have become positively charged by friction.

  8. Charging by Induction • If the balloon is brought near to a neutral object the charged region around it (its electric field) will affect the electrons in the neutral object. It will make them move away from it – giving the surface of the neutral object near to the balloon a positive charge. • The balloon will then be attracted to it and will stick to it.
