Question

Working of geyser with picture

Answer 1

Geyser works on the principle of conversion of electrical energy into heat energy.
construction:
There are two pipelines, one for inlet of cold water and other for the hot water.
The water tanks is fitted with heating elements which are controlled by thermostats.
the tank is normally covered with some insulating material such as glass wool  and entire assembly is enclosed inside a metal casing which can be hanged on a walled.
working:
when you switch on electricity, the elements get heated. Cold water collected into geyser tank gets heated to a certain temperature.
Thermostat cuts off the electric supply to geyser, once the water inside the tank is heated to certain temperature.
There are two LED lights one is red and other is green.
when the element is heated up, red light glows and when the element stops working green light glows.
Cold water in the geyser come in through seperate inlet and hot water goes out through separate outlet.
