Answer 1

Answer #1

using kVL in left loop

(120 + 74) i1 + 56 (i1 + i2) = 5.8 + 7

250 i1 + 56 i2 = 12.8... (i)

using kVL in right loop

(135 + 56) i2 + 56 i1 = - 3

56 i1 + 191 i2 = - 3...(ii)

solving (i) and (ii) (and considering the naming of current from the fig)

I1 = 0.02526 A

I2 = 0.05856 A

I3 = - 0.0329 A

(If the 10.0 V battery was not present, we could reduce the remaining circuit with series and parallel combinations.) Categorize: Because the circuit is not a simple series and parallel combination of resistances, this problem is one in which we must use Kirchhoff's rules. Analyze:...
