Homework Statement
So the first part is to find Voc in this circuit:
So I did this:
-10 + 1200*i1 + 3300*(i1 - i2) - 12 = 0
since i2 = 0 A,
-22 + 4500*i1 = 0
i1 = 22/4500 A = 0.0049 A
Then, for Voc:
3300*(i2 - i1) + Voc + 12 = 0
since i2 = 0 A,
3300*(−22/4500) + Voc + 12 = 0
Voc = 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(i2 - i1) + 12 = 0
3300(i2 - 0.0049) + 12 = 0
3300i2 - 16.137 + 12 = 0
3300i2 = 4.137
i2 = 0.001254 A
.:. Isc = 0.00125 A
Would this be correct? Thanks in advance for any help given. :)
