Ever since the introduction of electric tea kettles a few decades ago, it has made boiling water very easy. In the old days, boiling water was done by putting a kettle on a stove and boiling it. Although these old kettles are good with boiling water, it requires effort and constant monitoring. They have no auto power switch to stop the boiling and no temperate control. Also, it can take at least eight or nine minutes to fully boil water.

Sometimes, simple is best. A very cheap and easy tea kettle that will suit for all your water heating needs is also available in the market. It holds up to a quart and will heat your water to boiling quickly. Also, electric kettles help you in selecting the water temperature as per the needs.

Stainless steel kettles are preferred because they last a lot more durable and retain heat. A lot of the budget and cheap electric kettles are made out of plastic. Features like easy pouring, filling and handling attract most of the homeowners.

An electric kettle consists of a sealed heating element over which a canister rests to hold the water to be heated. Detachable canisters are also available to ease cleaning. To operate the kettle, several switches are mounted on sides of the kettle.

As the current flows through the plug and the connection, the resistor as a heating element becomes extremely hot and disperses the heat throughout the water, at this stage you see tiny bubbles rising from the element. After a minute or so, the water reaches boiling point, starts to agitate, and the steam comes out of the spout of the kettle.

Apart from the heating element, an electric kettle also comprise of a thermostat that controls the heating element. The higher you set the temperature, the lower the resistance is. A small current runs through the thermostat, usually controlling an electronic switch called a transistor.

At time when the resistance has greater value, the flow of current reduces thereby reducing the current flow in the heating element. This causes the heating element to cool. Further the water also gets cooler. On the other hand, if the resistance has less value, more current flow through the thermostat and the transistor. Thus, you are provided with the warm water.

This is how, the entire process of water boiling and tea preparation is accomplished with the electric kettle.
