1.(a) What is the value of R_{eq}
for the series combination of resistances shown below? (R_{1} =
33,300W, R_{2} = 11,100W,
and R_{3} = 5550W)

(b) If the current flowing through R_{1}
is 0.5A, what must be the current through each of the resistances R_{2}
and R_{3}?

(c) What is the potential difference across
R_{3}?

2.(a) What is the value of R_{eq}
for the parallel network of resistances shown below? (R_{1} = 250W,
R_{2} = 3330W, and R_{3} = 167W)

(b) What total current would flow through the network if a potential difference of 10 V were applied across it?

(c) What current would flow through each of the resistances?

3. For the series-parallel arrangement of conductors find: V_{AB},V_{BC},
V_{AC} and the current
through each of the parallel paths.(R_{1} = 8330W,
R_{2} = 2500W, and R_{3} = 10000W)
