Parallel Circuits 
1. Prepare a section in your notes for parallel circuits. Setup in your notes a data table for parallel circuits. Draw the circuit in your notes.
2. Connect the parallel circuit shown using the C resistors for both R1 and R2. Then record the following measurements into the data table.

- Measure the total current (I) in the circuit.
Do this by selecting one point in the circuit outside of the two parallel resistors and break the circuit there. Place the current meter into where you broke the circuit. Press on the switch to complete the circuit and measure the current.
- Measure the total voltage (Vtot) across R1 and R2.
Do this by connecting the voltmeter across the R1 and R2 resistors. Press on the switch to complete the circuit and read this voltage.
- Measure the voltage (V1) across R1.
Connect the leads of the Voltage meter across resistor R1 and measure the potential by completing the circuit with the switch.
- Measure the voltage (V2) across R2.
Connect the leads of the Voltage meter across resistor R2. Press on the switch to complete the circuit and read this potential.
6. Repeat the steps with a C resistor for both R1 and a D resistor substituted for R2.
7. Repeat the steps using the D resistors used for both R1 and R2.
