Consider the three identical light bulbs shown in the circuit. Bulbs B and C are wired in series with each other and are wired in parallel with bulb A. When the bulbs are connected to the battery as shown, how does the brightness of each bulb compare to the others? Don't forget to write your explanation on your scratch work and upload at the end of this exam for partial credit. Bulbs B and Care equally bright, but bulb A...

a.When two resistors RA and RB are combined in series and connected to a battery it is observed that the ratio of the power dissipated in RA to that dissipated in RB is equal to 10. If this arrangement is dismantled and the same two resistors connected in parallel to the same battery, what is the ratio of the power dissipated in RA to that dissipated in RB in this new circuit? b.How much energy is converted by a 12...

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...

In this tutorial you will analyse a solar powered Christmas tree. The tree has a solar panel at the top, a battery at the base, and bulb string lights around it. The bulb string lights are made from 4 parallel strings with 8 light bulbs in series each. Each light bulb has a nominal resistance of 8 2. The resistance of the wiring is negligible. The battery is charged during the day to keep the bulb string lights shining at...
