A kettle converts electrical work to a thermal energy store

Disadvantages of the Heating Effect

It results in energy loss, reducing efficiency

Absolutely brilliant, both my girls used it for A levels and GCSE. It's saves on paper copies, also beneficial exam questions ranked from easy to hard. It's removed a lot of stress from the exams.
