Can you please help me with this thevenin problem ??? Please guys can you help me with this?? http://forum.allaboutcircuits.com/cache.php?url=http://s14.postimage.org/9eysbodr5/image.png [Broken] I set all sources to 0 so we have Rth=3.667 KΩ then using superposition and remove the current source and replace it with open circuit so we have Vth1 =-3.333 V then remove the voltage source and replace it with short circuit so we have Vth2=25 V so Vth=25-3.3333=21.667 V other friends tell me that Vth2=30 V what's the correct ??
