Chapter 24.1, Problem 1cTH
The three long−filament bulbs are replaced by a small bulb and a large triangle−shaped bulb as shown at right.
One the diagram, sketch what you would see on the screen when the bulbs on. The scale of your sketch should be consistent with your answer to part a. Explain how you determined your answer.

9 V
B. The circuit at right is made from an ideal battery
connected to 4 ideal resistors as shown.
i.
What is the total resistance of this circuit?
Show your work.
R4= 352
R1 = 152
R3 = 452
ii.
Find the current through each of the 4
resistors. Show your work.
R2= 752
iii.
Rank the potential difference across the 4 resistors from greatest to least. Explain
your reasoning.
iv.
If resistor R3 is cut out of the circuit, without replacing it with anything, will the
current through resistor R2 increase, decrease, or stay the same? Explain your answer or
show your work.
A battery of voltage V₂ is connected to several identical bulbs of
resistance Ro, as shown in the circuit diagram at right. For both parts
of this question the switch is closed.
b)
Rank the brightness of the five bulbs when the
switch is closed. Explain your reasoning qualitatively (without
math).
Determine an expression for the current through bulb 4 in terms of V₂ and Ro
again, when the switch is closed. Show your work and explain your reasoning.
Read
Suppose you have two identical objects, A and B, in thermal contact with
one another. Model each as having 25 “bins" for thermal energy. At the
start, A has 7 "packets" of thermal energy and B has three as shown
schematically in the figure at the right. Assume that only one packet of
energy can go in each bin and that the energy packets are
indistinguishable.
Do
1. How many microstates are there for A initially? For B?
2. If two "packets" of thermal energy move from A to B, find the changes
of entropy, ASA, ASB, and Stotal as a multiple of KB.
3. Discuss how your result for 2 is consistent with the movement of this
thermal energy being spontaneous.
