Table 3: Measured Currents and Observed Bulb’s Brightness for the CircuitsQuestions on Measurement #2:1.Is the measured current in Table 3 increasing or decreasing with increasingthe number of bulbs from Fig.2 (a) to Fig.2 (b)? Why?
2.Is there any correlation between the measured current and observed bulbs brightness listed in Table 3? If yes, is the correlation consistent with P= IV=I^2R?
3.Are the lights at your home connected in series? Why?
