Layout #1 Compare the brightness of the bulb in the 1st circuit you built to the 3rd circuit you built with 2 bulbs.
a)
1 bulb shines brighter than 2 bulbs in a series circuit
b)
2 bulbs shines brighter than 1 bulb in a series circuit
c)
1 bulb and 2 bulbs shine with the same brightness
8.
Layout #1 What type of circuit did you build?
a)
series
b)
parallel
9.
Layout #1 What happens when the switch is open in circuit 2?
a)
The light turns on
b)
The light turns off
10.
Layout #1 Did the bulbs light in the fourth circuit you built Explain
a)
No, because the switch is open.
b)
No, because the broken light bulb makes the circuit incomplete.
c)
Yes, because they are connected in series.
11.
Layout #2 Does the resistance increase or decrease each time a fan was added?
a)
increase
b)
decrease
12.
Layout #2 What happens in circuit 2 if you close one switch and open the other?
a)
The fan stays on
b)
The fan stops working
13.
Layout #3 Did the broken light bulb in circuit 2 affect the other light bulbs? Explain
a)
Yes, because the other bulbs stopped working because they are on the same path
b)
No because the other bulbs stay lit because they are on separate paths.
14.
Layout #3 Why do the fans in circuit 5 run faster than multiple fans being used in Circuit Layout 2?
Answer: Fans in Layout #3 are in parallel and have their own branch. Fans in Layout 2 are in series so there share current which cause the fans to run slower.
Answer: Fans in Layout #3 are in parallel and have their own branch. Fans in Layout 2 are in series so there share current which cause the fans to run slower.
a)
True
b)
False
15.
Layout #2 What type of circuit did you build
a)
series
b)
parallel
16.
Layout #2 Was there a difference in fan speed on 1,3,4,5?
a)
yes
b)
no
17.
Layout #3 What type of circuit did you build in this layout? Explain
a)
Series because there is one path for current to flow
b)
Series because there are several paths for the current to take
c)
Parallel because there is one path for current to flow
d)
Parallel because there are several paths for the current to take
18.
Layout #3 Did the light bulbs that worked in the circuit 1 and 2 shine with the same brightness?
a)
Yes
b)
No
19.
Layout #3 Did the fans in circuit 5 run at the same speed?
a)
Yes
b)
No
20.

a)
series
b)
parallel
c)
series and parallel
