How does the heat produced by die passage of current in a metallic wir

1.	How does the heat produced by die passage of current in a metallic wire depend on: (i) the current in the wire (ii) the resistance of the wire, and (iii) the time of passage of current in the wire?
Answer» (i) The heat produced is proportional to the square of current passed in the wire. (ii) The heat produced is proportional to the resistance of the wire. (iii) The heat produced is proportional to the time of passage of current in the wire.
