Build an Electric Circuit:

As you work through the steps in the lab procedure, record your experimental values and the results on this worksheet. Use the exact values you record for your data to make later calculations. Do not enter negative numbers for voltage, current, or power even though you may have negative numbers as a result of doing the experiment. Convert all negative values of voltage, current, and/or power to positive values before entering data in the lab report. Do not include units in your answers.
