Problem 3 (Choosing the correct ranking for parts a and b are worth 5 points per part for a total of 10 points)
Page 6 of 7
In the circuit shown in the figure P3, each battery is delivering energy to the circuit by electrical transmission. All the resistors have equal resistance.
12 V
Ranking Choices:
i. b>c>a=e>d
ii. ad > b=c>e
iii. e > a=b>c=d
iv. c=d>b>a>e
d
+
9 V
Figure P3
(a) Rank the electric potentials at points a, b, c, d, and e from highest to lowest, noting any cases of equality in the ranking.
(Your response must include the ranking using the letters associated with the points in the circuit: a, b, c, d, and e. A response of i, ii, iii, or iv corresponding to the correct ranking will receive only 2 points.)
ii. ad > b=c>e
(b) Rank the magnitudes of the currents at points a, b, c, d, and e from greatest to least, noting any cases of equality.
(Your response must include the ranking using the letters associated with the points in the circuit: a, b, c, d, and e. A response of i, ii, iii, or iv corresponding to the correct ranking will receive only 2 points.)
>a=>d=c
