Teaching Guidance for 14-16 Supporting Physics Teaching

Practical concerns are the focus of this episode

The focus of this episode is on putting electricity to work in different kinds of electrical appliances. We see how it's possible to get students thinking about questions such as How long will the job take? and How efficient is the electrical appliance being used?.

Working out how to make a process better often involves cutting down on waste. When tracking energy or power, you'll be looking for energy dissipation or power switched to pathways that the designers of the system did not plan on.
