Hi all,
I am solving the circuit shown in the attachment by nodal analysis, I have already solved it using mesh and thevenins an am now trying to solve using Nodal analysis. I have come up with 3 nodal equations but when solving them iam getting a different answer to that of mesh and thevenins theorems. The 3 nodal equations I have determined are as follows could anyone tell me if I have made a mistake in them. the aim is to calculate the voltage across the 4 ohm resistor which is 2V.
Node A:
0 = (-Vb/2) + (17Va/10) - (Vc/2)
Node B:
11 = (Vb/2) - (Va/2)
Node C:
-5 = (-Va/5) + (9/20 Vc)
