When we connect a number of light bulbs in a circuit with a
battery, we can use our models of current, resistance, and
Kirchhoff's principles to predict the relative brightness of the
bulbs. If the bulbs are all identical, then the brightness of a
bulb will be an indicator of the current through that bulb (i.e., a
brighter bulb has more current).
1. The bulbs in the circuit shown on the right are all
identical. Predict which bulb or bulbs...
When four identical light bulbs are connected in parallel and
this combination is connected to an ideal battery, the bulbs each
glow with a certain brightness until the battery runs down after
six hours. [Recall that an ideal battery is one with no internal
resistance.] If two of the light bulbs are removed so that there
are just two light bulbs in parallel and then this combination is
connected to a new (but otherwise identical) battery, Question 6

10) You connect a number of identical light bulbs to an (ideal)
AA flashlight battery. (a) What happens to the brightness of each
bulb as more and more bulbs are added to the circuit in series? (b)
in parallel? (c) In which configuration will the battery last
longer? Explain your answers for each.

3c. Christmas lights sometimes come wired in parallel or in
series. Which variety do you prefer and state why?
Choose true or false for each statement regarding a parallel
plate capacitor..
true false The electric field is dependent on the charge
density on the plates.
true false The voltage of a disconnected charged
capacitor increases when the plate area is increased.
true false The voltage of a connected charged capacitor
decreases when the plates are brought closer together.

Draw a series circuit with a battery, wires, and more than 3
light bulbs. You decide the features: the battery's voltage, the
number of light bulbs, and the resistance in each light bulb.
Answer the following questions regarding your circuit:
1. What is the voltage for each bulb?
2. What is the circuit's resistance?
3. What is the current at any point in the circuit?
