• 6 V
• 3 V
• 2 V
• 1 V

Find Current

• 50 mA
• 0.5 mA
• 5 mA
• 500 mA

A series circuit has ____ path(s) that the electric current can take. 

• One
• Two 
• Three 
• Four

In a parallel circuit, if one connection is broken, all of the connections stop working.

• True
• False

• i1 + i5 +i4 = i2 + i3

• i1 + i5 +i3 = i2 + i4

• i5 + i2 +i4 = i1 + i3

• i1 + i5 = i2 + i3 + i4

• Circuit X is brighter than circuit Y
• Circuit Y is brighter than circuit X
• Both circuits have the same brightness
• Neither circuit will light the bulbs

• A₂ = A₃
• A₂ + A₃ = A₁
• A₁ + A₂ = A₃
• A₄ = A₂ - A₃

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

• The first bulb gets brighter
• The second bulb will be as bright as the first because they both get full power
• The circuit will no longer work
• Both bulbs will be half as bright because the voltage is divided by two now

The picture shows an electrical circuit. This circuit is a series circuit because: 

• It has 3 light bulbs.
• The same current flows through all three light bulbs.
• It uses a single battery.
• The electrical current has more than one path to flow through

What is a Parallel circuit? 

• Has only one path 
• Has more than one path 
• Allows energy to travel through easily 
• Has only one light bulb
