Answer 1

Air heater and Water heater. Basically the amount of heat depends on the resistance of the element and so higher the resistance more the heating. they are directly proportional to each other.

Two element containing devices are bulb and heater.

Bulb contains tungsten wire and heater has nichrome wire.

Here resistivity is VERY high so electricity doesn't passes and it turns into heat energy
