Answer:
The process looks a little something like this:
Explanation:
1. When the kettle is turned on, a large electric current flows through the coil, or the ‘heating element’.
2. The coil has an electrical resistance (a measure of the difficulty to pass an electric current through it). This resistance turns electrical energy into heat as it passes through coil.
3. The heat brings the water inside it to boiling point.
4. Some kettles use a thermostat, which prompts them to switch off when the water reaches the right temperature.
