1.
What is a circuit?
a)
The path of magnetic fields
b)
The arrangement of batteries in a device
c)
The route electricity follows in loop
d)
The path of least resistance
2.
If you increase the total voltage in a circuit how will it affect the light bulb? 
a)
The light bulb will stay the same
b)
It will burn out
c)
The bulb will get brighter
d)
It will get dimmer
3.

What are the two types of circuits called

a)

Linear & Parallel

b)

Series & Parallel

c)

Complete & Partial

d)

Series & Composite

4.
Why are resistors important in some circuits?
a)
Becuase they slow down the flow of electrons so the circuit doesn't over heat
b)
Because they protect against loss of charg
c)
Because they complete the circuit
d)
Because they control the flow of energy up and down
5.
What is a series circuit?
a)
The transfer of electrons from one object to another
b)
A circuit with a single path the current follows
c)
A circuit that goes in multiple directions
d)
A circuit that takes place in a series of events
6.

How is a parallel circuit different from a series?

a)

It has multiple paths for the current to follow

b)

It has many branches that get weaker farther from the battery

c)

They are two circuits running side by side

d)

They are the same thing

7.

What happens when you add a second bulb to a series circuit?

a)

The first bulb gets brighter

b)

The second bulb will be as bright as the first because they both get full power

c)

The circuit will no longer work

d)

Both bulbs will be half as bright because the voltage is divided

8.
Why are parallel circuits more commonly used in houses?
a)
Because they are faster than series
b)
Because if one light has a problem the rest will still work
c)
Because they are easier for electricians to wire
d)
Because they use less electricity
9.

c)
Parallel
d)
Broken

11.
What is this circuit missing?
a)
A resistor
b)
A wire
c)
A battery
d)
A bulb
12.

What will the bulbs look like when this circuit is turned on?

a)

They will be equally bright, getting full voltage

b)

The one in the middle will be brighter than the one on top

c)

The one on top on will be brighter than the middle one

d)

This circuit does not work

13.

Which type of circuit would be better in school building, and WHY?

4 lines
14.

In which type of circuit does it matter of you break a light bulb?

a)

Parallel

b)

Linear

c)

Series

d)

Partial

15.

How can you tell this is a series circuit?

a)

Because there is only one path for electrons to travel

b)

Because there are multiple paths for electrons to travel

c)

Becasue it has a switch

d)

Becasue it the bulbs are equally bright

16.

What do the lights in a series circuit get dimmer the more light bulbs you add to the circuit?

4 lines
17.

How can you tell what type of circuit this is?

a)

It's series becsaue the lights are the same brightness

b)

It's parallel because there are multiple pathways to the battery

c)

It's parallel becasue two lights are less bright than one light

d)

It's series becasue the bulbs are in order

18.

Why do electrons travel faster in a parallel circuit?

a)

Becasue they have more energy

b)

Becasue they lights are pulling on tehm more

c)

Becasue they have to get full voltage to each light

d)

Becasue the lights are using less energy
