Part 1-Series-Parallel Circuits
Theory:
1. Create a personal checklist (below) to demonstratemethods of simplification of series-parallel circuits. Your checklist should contain the following:
- Guidelines for series-parallel simplification
- The logical order of each step
- The formulas used at each step
Preparation:
2. For the following circuit, what is the voltage at VA(see below)?

3. For the following circuit, what value must R1 and R2 be to safely light the lamp? Assume that the current through R2 is 10% of the value of the current through the lamp.What must be the voltage drop across R1? What is the total current though R1?

Wiring:Looking at the circuit diagram, which components should be connected to the positive power bus? Which components should be connected to ground?
Test Procedure:
1. Record the measured results for each of the load resistors, node A from Lab 3 Tables 3-3, 3-4, and 3-5
