Simple application of nodal analysis

[PainterGuy]

Hi,

Almost all the details you will find in the given link below:

You will find the expected (or, target answers) in the top right corner.

As you can see my value for V1 is utterly wrong. It should have been 37.818V according to the answer given in the book. I have checked my equations several times but I found nothing wrong with them. Please help me with it. Many thanks for your help.

Cheers

You have the two equations as follows:

1 ... 3(V1) - 2(V2) = 48
2 ... 10(V1) - 14(V2) = -80

You copied the -14 into your matrix as -4. If you put in -14 you should get the right answer.

Silly mistake and trivial to find.

Many thanks, Zryn. You are so nice. You have helped me a lot.
