 1.(a) What is the value of Req for the series combination of resistances shown below? (R1 = 33,300W, R2 = 11,100W, and R3 = 5550W)
(b) If the current flowing through R1 is 0.5A, what must be the current through each of the resistances R2 and R3?
(c) What is the potential difference across R3?

 2.(a) What is the value of Req for the parallel network of resistances shown below? (R1 = 250W, R2 = 3330W, and R3 = 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: VAB,VBC, VAC and the current through each of the parallel paths.(R1 = 8330W, R2 = 2500W, and R3 = 10000W)
