Source Voltage Cases Measured Current (mA) Observed bulbs’ brightness Bulb 1 Bulb 2 Bulb 3 Bulb 4 V s = 5V All 4 light bulbs are in circuit 138.6 Dim X X Dim V s = 10V All 4 light bulbs are in circuit 195.4 Bright Dim Dim Bright Bulb 1 removed 0 X X X X Bulb 2 removed 164.0 Dim X Dim Dim Bulb 3 removed 170.5 Dim Dim X Dim Bulb 4 removed 0 X X X x Analysis : Data analysis 1 1.) Do the calculated values agree with the measured values in Table 2?
Data analysis 2 1.) Is the measured current (in table 3) increasing or decreasing with increasing the number of bulbs from Fig. 2 (a) to Fig. 2 (d)? 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 2 R? 3.) Are the lights at your home connected in series? Why?

a. The lights in my home are not connected in series because it is not practical. If a light in a bedroom were to go out, all the lights throughout the house would also go out. Data analysis 3 1.) Is the measured current (in table 4) increasing or decreasing with increasing the number of bulbs from Fig. 3 (a) to Fig. 3 (d)? Why?
2.) Is there any correlation between the measured current and observed bulbs’ brightness? Why?
