Stage 1
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
Scene 1/3
The current is shared between the bulbs, so the more bulbs that are connected, the dimmer they are.
Scene 2/3
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.
Scene 3/3
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
Scene 1/3
For an electric current to flow through conducting materials, the pathway or circuit must be complete, in other words, there should not be gaps.
Scene 2/3
Symbols are used to represent the different parts of an electric circuit. Straight lines are then drawn connecting the parts together.
Scene 3/3
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.
Stage 2
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.
Stage 3
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.
