Kirchhoff’s rules
Combination of resistors and Kirchhoff’s Rules
Note: Remember to look for simple series and parallel combinations to simplify your circuit
before beginning the more complicated procedure required for more complex circuits.
Using theory (equations), find the current passing through each resistor below in the circuits
below. Then simulate the circuit in Electronics Workbench and verify your results. The solving
equations part of your report can be hand written. If you use Kirchhoff’s rules, draw the circuit,
explicitly assign currents on your circuit, draw the loops you use in applying Kirchhoff’s rules,
write down the resulting equations, show the algebra (or Excel spreadsheet), etc. Print out a
copy of the circuit with a meter reading out at least one of the desired results to include in your
report.
