Thevenin Theorem, Kirchoff's Voltage Law, mesh analysis
The Attempt at a Solution
I'm kind of confused as to how to approach this question as a whole because I'm getting put off from the two voltage sources.
I was thinking that maybe I could use mesh current analysis so then I'd get:
-10 + 1200([itex]i_{1}[/itex]) + 3300([itex]i_{1}[/itex] - [itex]i_{2}[/itex]) + 12 = 0
where [itex]i_{2}[/itex] = 0 since it's within an open circuit, so then
1200([itex]i_{1}[/itex]) + 3300([itex]i_{1}[/itex]) = -2
4500([itex]i_{1}[/itex]) = -2
[itex]i_{1}[/itex] = [itex]\frac{-2}{4500}[/itex] A
Then,
[itex]V_{oc}[/itex] = [itex]\frac{-2}{4500}[/itex] * 3300
[itex]V_{oc}[/itex] = 1.5 V
but that doesn't sound right, so I'm not sure how else to approach it. Thanks for help in advance!
