Transfer electrical energy into other forms of energy
Only need to identify transfers to kinetic energy and thermal energy
Blender and fan
Electrical energy transferred into kinetic energy of electric motors
Iron and kettle
Electrical energy transferred into thermal energy
Hairdryer and washing machine
Electrical energy transferred into both kinetic energy and thermal energy
Appliances can be divided into two main categories: those that transfer electrical energy into kinetic energy, and those that transfer electrical energy into thermal energy
Some appliances are designed to do both
Power rating
The rate at which energy is transferred, measured in watts (joules per second)
Appliances designed to generate thermal energy usually have a much higher power rating than those designed to generate kinetic energy
