describe electronic theory of frictional electricity.
Answers
Electricity is basically flow of charge, current being defined as rate of flow of charge. Hence if any two appropriate pairs of material are rubbed together, there will be exchange of number of electrons. Now if any one object gets positively charged it is ready to discharge and become neutral almost instantly, by absorbing electrons from any surface that can provide electrons. Hence if you connect a positively charged object to earth, charge will flow to the earth instantly. That's what we can call electricity.
The same can be explained for a negatively charged body. All we need to say more is that in some pairs of objects rubbed together, we get a pair of well charged bodies. These work well to demonstrate the frictional electricity. Friction just helps to relocate the electrons in different materials.
