Question

plzz explain flow of charges inside a wire

Answer 1

If we connect the conductor to a battery, potential difference between the ends of the conductor occurs. This potential difference creates an electric field towards to the positive end of the conductor to the negative end. Free charges inside this electric field are exerted a force F=q.E in this field. Under the effects of this force electrical charges starts to flow. This flow of charge is called electric current. If there is no potential difference then there won’t be flow of charge or electric current. We can make an analogy with heat transfer. As we discussed in earlier chapters, heat flows from matter having higher temperature to the lower temperature. In this case charges flows from higher potential to the lower potential.
