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...

In this set of exercises (in the pre-lab AND lab), we will test/make the following assumptions: A flow exists in a complete circuit from one terminal of the battery, through the rest of the circuit, back to the other terminal of the battery, through the battery and back around i. the circuit. We will call this flow electric current For identical bulbs, bulb brightness can be used as an indicator of the amount of current through that bulb: the brighter...

A simple series circuit consists of three identical bulbs, a
battery, and a wire with a switch as shown in the diagram. When the
switch is open, all three bulbs glow with the same brightness. Then
the switch is closed. When the switch is closed, the brightness of
bulb A (increased, decreased, remained the same), and the current
through the battery (increased, decreased, remained the same).
Pick the right answer and explain your
reasons.

1. Consider the following if you set up the circuits in the lab using light bulbs as your resistors. Would the bulbs continue to be lit for the following conditions? If so, would they be brighter (draw more current) or dimmer (draw less current)? a)Light bulb R2 burns out in the series circuit? b)Light bulb R1 burns out in the parallel circuit? c)Then light bulb R3 burns out in the parallel circuit? d)Light bulb R3 burns out in the series...
