Questions

Please answer the questions below.

Question 4.1

What do you believe the blue circles represent in the model?

Question 4.2

Describe 2 similarities and 2 differences between this model and the last one you used.

Question 4.3

What do you think causes resistance in circuit? Do you think it is possible to have zero resistance in a circuit? If so, how might this be useful in the real world?

Question 4.4

Based on your observations, what role might resistors have in electronic circuits? After all, resistors waste energy and increase your power bill…why use them?

Question 4.5

List 3 ways that you can decrease the current in the wire?

Question 4.6

List 3 ways that you can increase the current in the wire.
