So the first part is to find Voc in this circuit:

So I did this:

-10 + 1200*i_{1}+ 3300*(i_{1}- i_{2}) - 12 = 0

since i_{2}= 0 A,

-22 + 4500*i_{1}= 0

i_{1}= 22/4500 A = 0.0049 A

Then, for V_{oc}:

3300*(i_{2}- i_{1}) + V_{oc}+ 12 = 0

since i_{2}= 0 A,

3300*(−22/4500) + V_{oc}+ 12 = 0

V_{oc}= 62/15 V = 4.13 V

Then the next part is to find the short circuit current Isc in the same circuit:

Assuming that my calculations for i1 were right, let i1 = 0.0049

Isc = i2 so then do mesh current analysis for the second mesh, which will get:

3300(i_{2}- i_{1}) + 12 = 0

3300(i_{2}- 0.0049) + 12 = 0

3300i_{2}- 16.137 + 12 = 0

3300i_{2 }= 4.137

i_{2}= 0.001254 A

.:. I_{sc}= 0.00125 A

Would this be correct? Thanks in advance for any help given. :)
