| Sep 8, 2017 at 1:15 | comment | added | BeB00 | It's still using the superposition of voltages, you just don't try to solve any equations until you've finished the superposition. | |
| Sep 8, 2017 at 0:25 | comment | added | Smeboo | Yeah, I always learned that you can't use super position with a dependent source. Which makes it a bit challenging to follow your work. I assume you are still using the external source method but just solving with a different form of super position (than what I learned) correct? | |
| Sep 7, 2017 at 21:45 | comment | added | The Photon | I'm with Vladimir in the coments over there. That may be a valid way to solve circuits, but it's not what we usually call the superposition method. | |

| Sep 7, 2017 at 21:12 | comment | added | BeB00 | I'm not quite sure what you mean. Yes, if you connect 0V across the terminals, the dependent source will be 0V. When I simulate this circuit, V1 does seem to be equal to Vin. That link doesn't really explain why you shouldn't use superposition for dependent sources | |
| Sep 7, 2017 at 21:10 | comment | added | The Photon | Say you zero out all the sources except the dependent source. Now whatever is the input controlling the dependent source will be a 0 (voltage or current). So the dependent source output will be 0. Not very useful, nor will it give you a correct result. More detail here | |
| Sep 7, 2017 at 21:07 | comment | added | BeB00 | I'm pretty sure you can still apply superposition even with dependent sources, as long as you stick with variables instead of absolute voltages until you sum all the superpositions | |
