GCSE Science Revision: Electricity in the Home
In these videos, we take a good look at how electricity provides energy for us to use in our homes. First we explore what is meant by the power of appliances. We then look at how different appliances need different currents in order to provide the power that they need. After that, we explore direct current (DC) and alternating current (AC) and look at how we can use an oscilloscope to explore the features of these. We then look at how to wire a 3-pin plug and how fuses and Earth protect us from dangerous faults. Finally, we look at a device called a residual current circuit breaker (RCCB) which can also be used to protect us from electrocution.
