Electricity is not just movement of charges

 When we speak about current electricity or dynamic electricity ,we say that it is moving charges ,but it is not so .See the actual difference and explore it. 

Current electricity is divided into:

1. Direct current 

2.Alternating current 

In the  direct current ,there is flow of charges [electrons ]and there is actual transfer of charges .


whereas 

In the alternating current ,there is no flow of charges ,it is only transfer of vibrations or energies .If in the forward direction if charges moves by 1 nm then during the reverse flow ,the charges would move 1 nm ,hence no net flow of charges .So AC is only the passing of electric vibrations .In the transfer of the AC current ,a vibrating electron vibrates the next electron and hence ,it is just the  transfer of vibrations from one end to other. This is the reason that changing Magnetic fields are able to create disturbances or vibrations in the electrons and there by induce current . 


So Current has 2 definitions 

1.In DC current ,it is flow of charges 

2.In AC current ,it is just flow of vibrations /just energy.
