Explanation / Answer

right 6 & 4 are in series R1 = 6+4 = 10

15 & 10 are in parallel R2 = (15*10)/(15+10) = 6

R6 & left 6 are in series

Req = (6+R2) = 12 ohms

I = e/Req = 24/12 = 2 A

through 6 ohms left = 2 A

through 15 ohms = (2*10)/(15+10) = 0.8V

through 6 ohms right = 2-0.8 = 1.2 A

through 4 ohms = 1.2 A

part B)

cross 6 ohms left = 2*6 = 12 V

across 15 ohms = 0.8*15 = 12 V

across 6 ohms right = 1.2*6 = 7.2 V

across 4 ohms = 1.2*4 = 4.8 V
