    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...
