Network Analysis Question

[eyeanand]

Hello,

I was solving a problem stated in the below pic..


The method i tried was using thevenin's equivalent Voltage ....first find Rth and then Isc...now Rth comes out to be infinite....so irrespective of isc Vth would be infinite.....

is this approach correct //or some fault in it.

Kindly explain.

That symbol next to the "2A" is a constant current supply, it can deliver an infinite voltage, just as the voltage supply can deliver an infinite current.
