```Parallel Circuit Lab (Discovery)
PSI Physics – Electric Current &amp; Circuits
Name______________________
Date__________ Period_______
*Students should make sure to have at least one resistor in every circuit as to avoid
overheating the battery and breaking the ammeter.
Objectives
● Demonstrate the relationships of voltage, current, and resistance in parallel by building
multiple circuits.
● Calculate the resistance of each resistor.
Materials (per team)
● Battery (or DC Power Source)
● Connecting wires
● Two resistors (of unknown value)
● Knife switch
● Ammeter
● Voltmeter
Guiding Questions:
Which concepts/main ideas apply to this lab?
What equations apply to this lab?
How do you connect a voltmeter? An Ammeter?
What does it mean for a circuit to be in parallel?
In what ways will your materials be used and what will the measurements record?
How do they apply to your chosen equations?
A complete lab report must include:
❏ The materials you used and how you used them
❏ A detailed procedure describing how to setup the experiment
❏ Analysis of the data
❏ A conclusion:
