[S4 Physics PMCians]
What we did in 2 hours:
We managed to complete, with the aid of the additional lesson, the entire chapter of Practical Electricity in just 1 week! We learnt how to calculate Power in order to determine the brightness of a bulb, how to use the correct equation and method when presented with either a parallel or series circuit.
we also learnt the many safety features present in an electrical appliance, such as the fuse and the Earth wire.
What you take home:
Please watch this excellent video that shows clearly how an Earth wire works (in a Singapore household).
