Analysis
➀
Determine the net current flow into or out of each of the four “nodes” in the circuit.
➁ Determine the net voltage drop around at least three (3) of the six or so closed loops. Re-
member, if the potential goes up, treat the voltage drop as positive (+), while if the potential
goes down, treat it as negative (-).
Discussion
Use your experimental results to analyze the circuit you built in terms of Kirchhoff’s Rules.
Be specific and state the evidence for your conclusions.
Extension
Build the circuit below and apply the same procedure you used previously. Analyze it in
terms of Kirchhoff’s Rules. If possible, try to analyze the circuit ahead of time and compare
your measured values with the theoretically computed values.
