Series: Shedding Light on Electricity
In the second episode, we examine how lights, switches, and other electrical devices are all connected either in "series" or in "parallel" with each other. How do they wire up the lights in your house so that in some rooms the light switch turns on only one light but in other rooms the light switch switches on two (or more) lights? And how is everything wired up so as to allow us to turn the lights on and off in different rooms independently of one another. Well, don't wait at the terminal, jump on board. Show Less
In 'Sources of Electricity', we take a detailed look at where our electricity comes from: thermal and hydroelectric power stations, wind farms, and solar farms. We alo examine the advantages and disadvantages of these sources of electricity.
