estatic electrisity

1. charging by contact

   • The Law of Conservation of Charge The law of conservation of charge is observed in the induction charging process. Before charging starts, the overall charge of the system was zero. There were same numbers of protons and electrons within the two spheres. Electrons were induced into moving from sphere A to sphere B

2. free electrons .....

   • free electrons reside in atoms outer shell as valance electrons and are easliplucked off and carried aroundwhen acted upon by an " autside force "

3. polarizaton

   • is a property applying to transverse waves that specifies the geometrical orientation of the oscillations. In a transverse wave, the direction of the oscillation is perpendicular to the direction of motion of the wave. A simple example of a polarized transverse wave is vibrations traveling along a taut string
