Physics P1 3.1 Electrical appliances.

HideShow resource information
What are electrical appliances able to do at the flick of a switch?
Transfer electrical energy into useful energy.
1 of 10
What are the uses of everyday electrical appliances?
Heating, lighting, making objects move and creating sound and visual images.
2 of 10
What is an electrical appliance designed for?
A particular purpose and should waste as little energy as possible.
3 of 10
A lamp is a common electrical appliance, what energy does it transfer electrical energy into?
Light.
4 of 10
An electrical mixer is a common electrical appliance, what energy does it transfer electrical energy into?
Kinetic energy.
5 of 10
Speakers are common electrical appliances, what energy do they transfer electrical energy into?
Sound energy.
6 of 10
A television is a common electrical appliance, what energy does it transfer electrical energy into?
Light and sound energy.
7 of 10
How do many electrical appliances transfer energy and what is the downfall of this?
By heating, although this may be a useful transfer for example in a kettle but energy is often wasted, therefore appliances should be designed to waste as little energy as possible.
8 of 10
What useful energy transfer takes place in an electric drill?
Electrical energy to kinetic energy.
9 of 10
Which electrical appliance usefully transfers electrical energy into light energy and sound energy?
