In this 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?
