Can someone please explain a step to a solution? It's about nodal analysis

Click For Summary
SUMMARY

The discussion focuses on solving nodal analysis equations in electrical circuits, specifically using Ohm's Law (V=IR) to transition from nodal equations to voltage values. The participant identifies nodes V1 and V2 and attempts to derive the equations necessary to find V2. Key insights include the importance of correctly interpreting resistance values, such as the 1kΩ and 10kΩ resistors, and the impact of current sources on voltage calculations. The solution involves substituting known values and solving simultaneous equations to determine the voltage at node V2.

PREREQUISITES
  • Understanding of Nodal Analysis in circuit theory
  • Familiarity with Ohm's Law (V=IR)
  • Ability to solve simultaneous equations

Homework Equations



V=IR, Nodal Analysis

The Attempt at a Solution



1 and 2 in the diagram are the nodal equations. Considering that the left node is V1 and that the right node is V2. I don't know how to get from the nodal equations to step 3. I know that you go from step 3 to step 4 using V=IR.

I tried solving the nodal equations to get to step 3...

Can someone please work it out for me? Thank you

Please help

I assume from the picture that the 1kR label next to the 10kR on the left should actually be the resistance of the 2mA current source, which is interesting, since by Ohms Law the voltage across it would then be 2V, as shown by the 1st equation current of -2/K, yet this voltage is not V1 ... somehow, despite sharing terminals ... ?

Anyway, you know what the voltage and resistance are for Ix, so substitute that in and then do the algebra (solving simultaneous equations) and you should get the value for V2.
