Answer:

The flow of electrons or ions from a point to the another point through an electric conductor or a good conductor of electricity.

  • The flow of heat through a conductor is depends upon the cross section of wire and length of wire.
  • It mainly depends on the material of the conductor through which the current is flowing.

General formulae for current is-

V=IR

so,  I=\frac{V}{R}

Here, I denotes the flowing current though the conductor.

  • Best conductor of electricity is considered to be copper because it is cheap and flows good amount of electricity.

SI unit of current is Ampere denoted by symbol (A).
