8. There is a correlation between the measured current and the observed brightness listed in Table 3. The correlation is consistent with P = IV, because for each bulb the current increases while the voltage is the same. Therefore, the power produced by each bulb (observed brightness) would remain great. 9. The lights at my home are connected in parallel, because it is reliable. If one light goes out, the rest will remain on, because each bulb is independent of the others. 10. The maximum number of light bulbs that can be connected in parallel with the power supply is approximately 10 bulbs. If more than 10 light bulbs are connected in parallel with the power supply, it will short circuit.
