Homework Equations
KCL equation
The Attempt at a Solution
i tried to find using KCL.. is my equation right?
Loop equation 1:
EB + I3R3 + R1(I3 + I1) = 0
Loop equation 2:
R1(I1 + I3) + R2(I1 – I2) = 0
Loop equation 3:
EB + I3R3 + I2R2 = 0
can i use MESH analysis... but there are three unknowns and if i use mesh, i can only have 2 equations with 3 unknowns
