Engineering Circuit Analisis. Find voltage of 2 points

AI Thread Summary
The discussion focuses on finding the voltage V0 in a circuit using Kirchhoff's Voltage Law (KVL). The user sets up three equations based on KVL and relationships between voltages and currents. After solving these equations, they determine that VA equals -1.13V. Subsequently, they calculate V0 as 2.26V, confirming the solution's accuracy. The user expresses confidence in their final answer.

Circuit Analysis. Find V0 in the network

Homework Statement

I need to find V0


Homework Equations



I need to find V0

The Attempt at a Solution




I did KVL.
13 +Vx - 4Vx + 2I +2VA <----- 1st equation
Vx = 7I <----- 2nd equation
VA = 2I +2VA <----- 3ed equation


solve 3e eq. i got I = 1.5VA
then used that answer to solve 2nd eq. i got Vx = -3.5 VA

then i apply both those answers to solve 1st eq

13 -3.5VA + 14 VA -VA +2 VA =0
VA = -13/11= -1.13

therefore V0 = 2VA= 2.26V


Am i right?
