Feb 3, 2021 at 6:41 | comment | added | Israr | What i have learned from the above answer is: [1] We can take any direction for a particular mesh, not necessarily that same for all. [2] Make sure every branch current is been considered,[needs practice]. [3] Sign convention is utmost important, during the equation formation and afterwards calculating the parameters for any particular element. Thanks for Answer and excellent commentary below that. | |

Feb 2, 2021 at 20:01 | comment | added | jonk | @ElliotAlderson Neither of us can read the OPs mind and different people will come to different conclusions about that. So the point is moot. But I see a serious person there. If you don't, then your conclusion about the OP is itself perhaps harmful and at the very least, judgmental. But we will have to leave it there. We just disagree. (My opinion is getting stronger because just last fall I taught about 50 students EET221 and I've been getting more of a feeling for where they are at.) | |
Feb 2, 2021 at 19:59 | comment | added | Elliot Alderson | @jonk Sorry, I disagree. We have no knowledge of whether the OP will carefully study the answer to learn from their mistakes or they will copy down the provided equations and hand in the exam with no thought whatsoever. I think a much better approach is to say "Your second equation is incorrect, you forgot about..." and give the OP a chance to work through the rest of the problem. The potential downside of giving an answer is that it is unfair to students who don't cheat, so I try to avoid that. | |
Feb 2, 2021 at 19:48 | comment | added | jonk | @ElliotAlderson I think this is one of those cases where the OP has carefully shown their work and where the harm in showing a completed result is nil. In fact, it is actually better than otherwise as it allows the OP to study a now-worked example and learn for themselves several new things they missed. I can't see any harm to the OP here. Not at all. I think in this case you are administering "by rote" (automatic pilot, so to speak) rather than examining each situation and weighing its merits. | |
Feb 2, 2021 at 19:37 | comment | added | G36 | @ElliotAlderson I will keep that in mind next time. | |

Feb 2, 2021 at 19:29 | comment | added | G36 | Thenk for comment @jonk.And very good point about current source and that only one mesh current loop is allowed for the same current source. | |
Feb 2, 2021 at 19:20 | comment | added | jonk | Excellent approach. It keeps it down to two equations. One could include the \$I_1\$ loop equation by creating a voltage variable to recognize the drop across the current source and solve three: \$I_2\$, \$I_3\$, and the current source voltage value as unknowns, substituting in \$I_1\$'s value, later. (But when attempting that it is important that no two loops enclose the same current source as its loop current.) | |
