Electrical Circuits

Series or parallel circuit?
1. series
2. parallel
In this series circuit, if I unscrew light bulb H, what happens to light bulb J?
1. stays on
2. nothing
3. turns off
4. gets brighter
Which direction is the electricity flowing?
1. A B C D (clockwise)
2. K J I H (counterclockwise)
Notice that the lights are not on. At what letter is the problem?
(You might want to compare this picture and the previous one when the lights were working.)
1. A
2. C
3. E
4. H
5. J
The problem is with the battery going the opposite way. Why?
1. When the batteries go opposite directions they cause a break in the circuit.
2. The batteries are programmed to only work when going the same direction.
3. The batteries are pushing opposite directions, cancelling each other out.
4. The batteries going opposite ways caused the light bulbs to blow from too much force.
Series or parallel circuit?
1. series
2. parallel
In this parallel circuit, if I unscrew light bulb H, what will happen to light bulb I?
1. It will stay on.
2. It will turn off.
These two independent paths are known as what?
1. paths
2. branches
3. rows
4. columns
5. streams
If there are two independent branches they must have a point where the electricity splits. Where does the electricity split?
1. F
2. G
3. J
4. K
If the electricity splits at "G", where does it join back together?
1. F
2. G
3. J
4. K
Series or parallel circuit?
1. series
2. parallel
In this parallel circuit, where does the electricity split to go through the two branches?
1. F
2. G
3. H
4. I
5. L
6. M
If the electricity splits at "H", where do the branches join?
1. F
2. G
3. H
4. I
5. L
6. M
Notice that light "K" is not lit. At which letter is the problem located?
1. G
2. H
3. J
4. L
5. M
6. N
Are the lights in parallel or in series?
1. series
2. parallel
What letter is next to what keeps light "K" off?
1. E
2. G
3. I
4. J
5. K
6. L
The wire "J" is keeping light "K" off. Wire "J" is known as what?
1. a short-circuit
2. a spoiler wire
3. a by-pass wire
4. a potential energy wire
The short-circuit "J" causes the electricity to by-pass light "K" because:
1. Wire J has more resistance than light K.
2. Wire J has less resistance than light K.
3. Wire J is not curved as much as light "K's" path.
4. Wire J disconnects the wire going to light K.
