I1 (45) + I2 (−10) + I3 (20) = 0
I2 = 0.1
I 1(20) + I2 (5) + I3 (25) = 15

The current through R1 is approximately -0.47 A in a counter clockwise direction toward
node c and 0.47 A in a clockwise direction away from node c.
The current through R2 is approximately 0.97 A in a counter clockwise direction toward node
A.
b) The electric potential measured at node C. (5 points)
