5. Writing: Describing Circuit Diagrams

Now, you are going to see some of the components listed in the previous tasks connected in two different circuits. Look at this picture (from: https://www.bbc.co.uk/bitesize/guides/zk37hyc/revision/2) and think about the answers to these questions:

1)      Which of the diagrams are conventional circuit diagrams and which are pictorial?

2)      What do the circuits consist of?

3)      How do you make the circuits work?

4)      How do A and B work?

5)      What is the difference between A and B?

6)      What happens if one of the bulbs blows out?

To answer the questions, fill in the description in this task.

 

Now, let´s have a look at three more circuits that are a little bit more complex than the previous ones: diagram 1, diagram 2 and diagram 3. Here is a set of questions concerning these three diagrams:

1)      What components do the circuits consist of?

2)      In what ways are the circuits similar and in what ways are they different?

3)      500 mA is the current measured using the ammeter. Is it possible to calculate this value instead of measuring it? If so, how?

4)      Suppose diagrams 2 and 3 are simplified versions of diagram 1. Why is the value across R123 = 20 Ω? Why do electrical engineers sometimes need to do such calculations?

Answer the questions by completing this task.

 

Finally, it´s time to describe a circuit without any clues given. Just choose whatever electrical components you wish and draw a simple electrical circuit showing the wiring. Describe the diagram by answering the following questions:

1)      What components does the circuit consist of?

2)      How is it wired/connected? (in a series/in parallel)

3)      How do you make the circuits work?

4)      What is the circuit used for/in? What is the function of the individual components?

5)      What happens if you…(complete the question)?

6)      Are there any calculations needed? If so, please, specify + explain the reasons why.
