Problem with node analysis
July 11, 2021 - 12:27am

Can someone explain to me what i'm doing wrong?

Vo = 4V

- 2  + ( Vx / 3k ) + ( Vx / 6000 ) = 0

12000  = - 2000Vx  - Vx 

12000 / - 2001 = Vx 

Vx = ~ 6v

Simple solution -

The driving capability of the current source is 2mA.

 

The at the Vx point the current should be = (vx/3000Ohms) + (vx/6000)

Since the current driving source can not be more than 2mA,

 

0.002A = (vx/3000Ohms)A + (vx/6000)A

Vx = 4V.

Since it is the same node Vx = Vout.
