Consider four identical bulbs connected in series to a battery. A fifth bulb is then connected in parallel with the first four. What will this additional connection do? Please explain why.
a) Increase the illumination produced by bulbs connected in series
b) Decrease the illumination produced by bulbs in series
c) Tt will change the illumination shomehow, but we need to know the voltage on battery and resistances of bulbs to answer
d) Leave the illumination produced by bulbs in series unchanged

A Investigation #11: Non-Identical Bulbs in Series and Parallel All of the circuits you have investigated so far have involved identical bulbs. If two bulbs are identical and one bulb is brighter, then the brighter bulb must have a larger current thru it. Furthermore, the larger current must be caused by a larger potential difference. In this investigation, you will study circuits for which the bulbs are not identical. We will illustrate that two Spherical bulbs are not identical by...
