- 4. Multiple Choice
What is the difference in finding total resistance in a series circuit vs. in a Parallel circuit?
No Difference
For series use inverse equation, for parallel add resistances up.
For series add up resistances, for parallel add up resistances
For series add up resistances, for parallel use inverse equation

- 8. Multiple Choice
If a series circuit of three bulbs is rearranged into a parallel circuit, what will happen to the brightness of three bulbs
The bulbs will turn off due to an incomplete supply of electricity.
All three bulbs will have the same amount of luminosity once rearranged into a parallel circuit but will be dimmer than in parallel.
All three bulbs will have the same amount of luminosity once rearranged into a parallel circuit but will be brighter than in parallel.
The bulb next to the battery will be brightest and each bulb will be dimmer than the one before.

Johnny and Sam are working on a physics lab together. In their lab, they are to create both a series circuit and a parallel circuit using identical materials. Johnny constructs the series circuit while Sam makes the parallel circuit. After observing the two circuits, Sam argues that his circuit contains more resistance than Johnny's circuit. Johnny says that Sam is wrong, and that his circuit has more resistance. Who is correct?
Sam is correct, the parallel circuit has more paths for the electricity to travel, making the resistance greater.
Sam is correct, the parallel circuit's light(s) is brighter, meaning there is more resistance.
Johnny is correct, parallel circuits have LESS resistance because the current is greater.
Johnny is correct, parallel circuits have LESS resistance because their resistors add inversely, while the resistors in series circuits add normally.
