Measuring Circuits

Circuit 1 please label R1, R2, and R3 on the diagram

1 - Measure the voltage across each bulb.

2 - Use the Power Supply measurements to fill out V and I for the Source

3 - Use your Bulb Look Up Chart to record a value for current that matches the value for the bulb’s voltage,

4 - Calculate power and resistance for each bulb.

Total the power used by of all of the bulbs and compare to the power output of the source. % error = (source power - bulb power)/(source power)

Were all of the bulbs equally bright? Why or why not?
