With both kettles, it's not recommended that you leave water in the kettle after use and reboil it. Leaving water in either of the two for too long can give the water a strange aftertaste. Always try to boil only what you need.
Hope it helps!!

Answer:
The resistance of the kettle remains constant.
Energy dissipated =Pt or VI×t as P=VI.
