There are two main reasons for this. Firstly, most electric kettles are properly insulated. Secondly, the heating coil sits directly in the water, meaning less heat is lost to the air. While ...

An electric kettle, typically made of plastic or steel, has a heating element on the bottom. The kettle is plugged into an electrical outlet, which powers the coil and heats up the water.

The power output is used to run a 2,000 W kettle. Calculate the current in the primary coil (the input current). (The power in each coil will be the same, since transformers are 100 per cent ...
