Chapter 6.1, Problem 2aT
Compare the brightness of the two bulb with each other. (Pay attention to large differences in brightness. You may notice minor differences if two “identical" bulbs are, in fact, not quite identical.)
Use the assumptions we have made in developing our model for
1. Is current “used up” in the first bulb, or is the current the same trough both bulb?
2. Do you think that switching the order of the bulbs might make a difference? Check your answer.
3. On the basis of your observations alone, can you tell the direction of the flow through the circuit?

3. The new symbol you see in the diagram at the left is a multicell battery (like a 9V), which is
made up of a number of smaller single cell batteries (like a 1.5V). Let's say its total voltage is V.
A. Which resistor takes the most voltage?
B.
What is the total resistance?
C.
In variables, what is the current in the circuit?
D.
How does the voltage used by the 2R compare with R?
E. In variables, what is the voltage used by the 2R resistor?
Answer the following questions.
1. Why does the voltage across the resistor for charging and discharging processes
change the sign from positive to negative? Hint: think about the direction of current.
2. Does the voltage V across the resistor for charging and discharging obey by the same
equation: V = Vo eRC
3. What is the sum of the voltages across the capacitor Vc and across the resistor VR at
any point in time during the charging and discharging processes?
Use a snipping tool to copy and paste the waveform chart and graph for the charging and
discharging curves into the lab report.
1. In Module 4, we learned the concept of electric current and resistance. Most circuits have
more than one resistor, often connected in series, parallel, or combination of series and
parallel.
(a) Imagine a circuit with two identical bulbs connected one after the other (in series) as
shown. Discuss how the brightness of the two bulbs will compare to the brightness of
an identical bulh in a single-bulb circuit. Explain your
reasoning.
(b) Now consider the circuit pictured to the right with the circuit branching to two bulbs
and back again. (Two bulbs connected in this way are said to be in parallel.) Discuss
how the brightness of the two bulbs will compare to the brightness of an identical
bulb in a single-bulb circuit. Explain your reasoning.
