Practical: Series vs Parallel Circuits Construct each circuit and get the teacher to check it. 6V Series Circuit 6V Parallel Circuit 6V Combination Series/Parallel Circuit Conclusion For the last circuit answer: 1. When a bulb is disconnected, what happens to the remaining bulb(s)? Why? 2. What is the real world application of the combination circuit? 3. What happens when the switch is open? Closed? Doorbell Challenge Mrs Mackity has recently built a new house which has a front door and a back door. Unfortunately, she has very little budget as she spent it all on the gardens. She cannot afford to buy two door bells so she would like to install a door bell which can be rung by either the front or the back door. Can you design a circuit with two switches representing the buttons for the doorbells and a single light bulb which represents the door bell. Draw it in the diagram below.
