I want you to work in pairs. First of all, I want you to watch video 1. And after that, I want you to watch video 2.
Here you will find the transcriptions for both video 1 and 2 in case you don't understand any word from the videos.
Video 1 Transcription
The current is shared between the bulbs, so the more bulbs that are connected, the dimmer they are.
Each bulb gets the full battery voltage, so at junction A the current splits, but each bulb still has the same current flowing through it as just one bulb in the circuit would have. That's why the bulbs glow brightly.
In a series circuit, when a bulb is removed, the circuit is broken. In a parallel circuit, even if a bulb is removed, there is still a complete circuit.
Video 2 transcription
For an electric current to flow through conducting materials, the pathway or circuit must be complete, in other words, there should not be gaps.
Symbols are used to represent the different parts of an electric circuit. Straight lines are then drawn connecting the parts together.
For a power supply, a long line and a short line, drawn together, are used. The long line represents the positive end or terminal. The short line represents the negative terminal.
Now, I want you to have a look at the information in a website which is included in the Resources tab of this lesson. You will find some questions in the website. I would like you to discuss them with your partner.
Finally, I want you to go to the website Wiggio and find the group I created. Thus, I would like you to record audio brief theoretical explanations of series and parallel circuits and other concepts learnt in former lessons. You must use the headset I have provided you with.
