Question

explain the flow of current in a metallic wire on the basis of the movement of the electrons? and also answer the questions 8 and 9

Answer 1

Electricity flows easily through a conductor because the electrons are free to move around in the object. Whenever there is a movement of electrons through a conductor, an electric current is created.Current can also be divided into two types- DC and AC.

Answer 2

below is how the current flow in a wire...

in a wire electrons move randomly in all directionsin the atoms.
when a wire is connected with the source of electricity, an electric force acts on electron, present in the wire which make them to move fron negative ti positive end.
this flow of electrons constitutes electric current in elwctric wire.


accorsing to ohm's law the current flowing in the conductor is directly proportional ro the potential difference at a given temperature.

i.e.V=IR (where I is constant called resistance of conductor)
R=V/I
