Advantages & Disadvantages
Advantages of the Heating Effect
- The heating effect is very useful in appliances which are intended to heat up, such as:
- Electric kettles
- Electric ovens
- Domestic heating
- Electric toasters
A kettle converts electrical work to a thermal energy store
Disadvantages of the Heating Effect
- It results in energy loss, reducing efficiency
- For example, waste heat in a light bulb or overheating in a computer
- It can pose a fire hazard – many domestic fires are caused by too much current passing through low-quality wiring
- For example, sparks or excessive heat in an electric motor
