Answer:

Work done in carrying a charge Q through a potential difference V is given as  

Also, Q =  I  t  

Using Ohm's law, V =  I R

W =  I^2Rt  

This work done in carrying the charge th rough the wire appears as the heat produced. i.e.,

H = V I t =  I^2 Rt.  

this energy is dissipated as heat energy.

This relationship is also known as Joule's Law of Heating
