Is the current through the power supply and each bulb (in Table 1) increasing or decreasing with increasing the number of bulbs from Fig. 4 (a) to Fig. 4 (d)? Why? 2. Is there any correlation between the current through each bulb and the observed bulbs' brightness listed in Table 1? If yes, is the correlation consistent with P = IV = 12R? 3. Are the lights at your home connected in series? Why?
