given this circuit find the current on R1,R2 and R2
Homework Equations
I = V/R
The Attempt at a Solution
i applied kirchhof's law and I have this:
36 - 5*I - I1*4 = 0
36 - 5*I + 20 - 2*I2 - 14 = 0
20 - 2*I2 - 14 + I1*4 = 0
and i find I1 = 66/19 which is wrong
the book says
I1 = 1.10 A
I2 = 5.21 A
I = 6.32 A
what am i doing wrong?
