What is Electric kettle?

Electric kettles were introduced as a means to boil water without the necessity of a stove top. They are normally constructed of durable plastic or steel and powered by mains electricity. In modern kettles the heating element is typically fully enclosed, with a power rating of 2–3 kW at 220V.

Jug kettles became popular in the late 20th century. They have a more upright design and are more economical to use, since small amounts of water, enough for only one cup, can be boiled while still keeping the element covered.

A kettle, sometimes called a tea kettle or teakettle, is a type of pot, typically metal, specialized for boiling water, with a lid, spout, and handle, or a small kitchen appliance of similar shape that functions in a self-contained manner.

History of Electric kettle:-

In the latter part of the 19th century, electric kettles were introduced as an alternative to stove top kettles. In 1893 the Crompton and Co. firm in the United Kingdom started featuring electric kettles in their catalogue. The early electric kettles were quite primitive as the heating element couldn't be immersed in the water. Instead, a separate compartment underneath the water storage area in the kettle was used to house the electric heating element. The design was inefficient even relative to the conventional stove-top kettles of the time.

In 1922, the problem was finally solved by Leslie Large, an engineer working at Bulpitt & Sons of Birmingham who designed an element of wire wound around a core and sheathed in a metal tube. As this element could be immersed directly into the water it made the new electric kettle much more efficient than stovetop kettles.

In 1955, the newly founded British company Russell Hobbs brought out its stainless steel K1 model as the first fully automatic kettle. A thermostat, triggered by the rising steam as the water would come to boil, would flex, thereby cutting off the current.

Modern kettles include a variety of technological advancements. Some electric kettles are cordless with illumination capabilities. Whistling kettles emit an audible sound as the water boils.

How Electric Kettle work?

Interestingly the kettle is a big silver box that is shaped like a penguin. When you plug the kettle into an electric socket it starts to make your cold water into scorching hot water.

Next you plug in the kettle this heat the coil, which heats the metal plate at the bottom, which heats your water.

After that since metal conducts heat very well it absorbs the heat from the wire and then spreads the heat evenly throughout the bottom plate. The electricity flows through the element inside the kettle .The flow of the electricity causes heat.

Electricity travels through the heating element which looks a bit like a worm and carry’s on until it reaches the water at the bottom of the kettle.

After the temperature reaches boiling point which is normally 100 degrees your water will now start bubbling, now you have your boiling water.
