प्रश्न
Name two precautions to be observed while using an immersion heater.
उत्तर
The two main precautions to be observed are:
(i) Never try to find the temperature of water by dipping your fingers in water because some times when water comes in contact with the live or neutral wire, there is a possibility of getting an electric shock.
(ii) The heater must be surrounded by water to the desired level before it is switched on. If not,
so the heat produced in the nichrome wire will not dissipate easily and so the heating element will melt.
