Question
Assertion : Wire through which current flows gets heated.
Reason : When current is drawn from a cell, chemical energy is converted into heat energy.

Answer

(c) When we supply current through the cell, chemical reactions takes place, sochemicalenergy of cell is converted into electrical energy. If a large amount of current is drawn from wire for a long time only then wire get heated.
