P1.3 - AQA GCSE Physics Unit 1 - Overview
P1.3 |
The usefulness of electrical appliances
We often use electrical appliances because they transfer energy at the flick of a switch. We can calculate how much energy is transferred by an appliance and how much the appliance costs to run.
Candidates should use their skills, knowledge and understanding to: |
| ■ compare the advantages and disadvantages of using different electrical appliances for a particular application |
Candidates will be required to compare different electrical appliances, using data provided.
Payback time and efficiency calculations may relate to such questions.
Ensure you know what how to work out kWh calculations |
| ■ consider the implications of instances when electricity is not available. |
Portable energy solutions - batteries, solar cells etc. that can be used when camping or when the electricity supply fails.
You need to be aware of health implications as well as inconvenience when no electricity is available.
In this digital age information is stored electronically and banking is heavily reliant on the electricity supply. |
There is only one section to this part of the syllabus:
P1.3.1 - Transferring electrical energy
There is also a page suggesting practical experiments that should be carried out during the study of this section.
