PHYSICS: SERIES CIRCUIT ANALYSIS
ASG#3
Purpose:
To measure electric currents, and potential differences in a series circuits using the PhET DC Kit.
Method:
1. Use the data table given to record your findings.
2. Open the PhET Circuit Construction Kit (DC only).
(Hint: do a google search for “phet dc only”)
3. Construct a simple series circuit using 1 battery and
3 light bulbs (see figure 1).
4. Right-click on the battery and change its voltage to
30 V. Right-click on the bulbs and change their
resistances to 10 S each (if they are not 10 S
already).
5. Use the voltmeter and non-contact ammeter (under
“Tools”) to measure and record the potential
differences (V) and currents (I) at the points
indicated in the diagrams (see figures 2 and 3).
6. Remove the bulb between A3 and A4 and
reconnect the wire. Repeat step 5.
