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...
1. Does the resistance of the WHOLE circuit increase, decrease, or stay the same when additional light bulbs are added in series? 2. Does the voltage across each individual light bulb increase, decrease, or stay the same when additional light bulbs are added in series? 3.

Are light bulbs brighter when they're connected in series or in parallel? 4. Consider a whole circuit. When the power supply is set to 12V, does the power supply provide more current to the...
Two light bulbs are connected in parallel, and then connected to a battery, as shown in Fig. 4.51(a). You observe that bulb 1 is twice as bright as bulb 2. Assuming that the brightness of a bulb is proportional to the power dissipated in the bulb’s resistor, which bulb’s resistor is larger, and by what factor? The bulbs are now connected in series ,as shown in Fig.4.51(b). Which bulb is brighter, and by what factor? How bright is each bulb...
Experiment RESISTANCE IN COMBINATION PURPOSE: To study series, parallel, and series.parallel combinations of resistors. EQUIPMENTThe experiment board and accompanying bundle of connecting wires. PROCEDURE: 1. Resistors in series: Connect the circuit shown in Fig. 1. Using circuit theory (Ohms Law in conjunction with the predicted procedure for combining resistors in series), calculate the expected current in or through the three resistors in series and the expected voltage across each of the three resistors. After the instructor has approved your connections,...
