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 (V_tot) 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.
