4. Using the measurements you have made above and your knowledge of Ohm’s law, calculate the equivalent resistance (Req) of the circuit for each of the three parallel circuits you tested. See data table. 5. Study the equivalent resistance readings for the parallel circuits. Do your results verify what is expected for Req from the Theory section?
