Question

Why does any material got heated, when electricity flow from it?

Answer 1

When electricity moves through anything -- wires or bodily tissues -- there are actual electrons (typically) moving. These electrons are being pulled along by an electric field, but they're also bumping into the atoms that make up the wire or bodily tissue. When an electron bumps into an atom, it transfers some of its kinetic energy to that atom. Temperature is just a form of kinetic energy, where you subtract the "bulk motion". If the atoms in the wire or the bodily tissue aren't moving, this means that all of the kinetic energy that gets transferred to them is measured as temperature. That is, the atoms heat up,this is called joule heating...nd dats the reason for materials to get heated up when electricity pasees thru it.hope this helps you.
