• parallel
• square

This is an example of a ______ circuit

• Series

What happens to my total resistance as I add more resistors to a parallel circuit?

• Increases 
• Decreases
• Stays the same
• No one really knows

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
