Find: I1, I2, I3 I and pd across each resistance in branch cd Find I in 4 ohm resistance Find
pd across ab, fc, and ed Find I1, I2, and I3
Solution
ex #3):
5 and 20 are in parallel , its effective R1 = 5*20/25 = 4
8 and 4 are in series its effctive is R1eff = 12
12 ,4, 6 are in parallel R2 = 2 .
2 and 22 are in series R2eff = 24 .
24, and 12 are in parallel, R3eff = 8
r, 1 and 8 are in series Reff = 10
= i / Reff
i = Reff = 27* 10 = 270 amps
