What is current I1?
What is current I2?
What is current I3? 14 V 10 13 4 12V 14 Dr. Birdwell asks that you solve for the currents as
shown. If the actual current is in the opposite direction as shown, specify it as a negative current.
EXAMPLE
Solution
Let potential at A and C =X
let potential at D=Y
and at B=14 V
(X-14)=I4x6
0-X=I2x10
X-Y=12xI5
Y-12-X=4xI1
I4+I5=I1+I2
((X-14)/6)+((X-Y)/12)=((Y-12-X)/4)+(-X/10)
(6X/10)-(Y/3)=-2/3
Y-14=14xI3
I3=I2-I4
((Y-14)/14)=(-X/10)-((X-14)/6)
(Y/14)+(4X/15)=10/3
(6X/10)-(Y/3)=-2/3
X=1340/166
Y=1372/83
I1=((Y-12-X)/4)=-0.8855 A
I2=(-X/10)=-0.8072A
I3=((Y-14)/14)=0.1807A.
