I tested a different mic setup with this video. Let me know how the audio levels are to you, like if the volume is too low or high on your device. Thanks!

Thanks a lot. 4 hours of lecture boiled down to 7 mins.

So glad I found these videos. Taking engineering courses finally and it’s a different approach to circuits compared to physics. Idk why they do that, it confuses students a lot.

Thank you, this seriously helped me with nodal analysis

Great video, i've watch from this to super mesh analysis and this video again for a review before my midterm test ! You've helped me a lots since i didn't quite understand about the lecturer said at class. Again, thank you !

Had to at least add one comment after watching several of your videos. THANK

what about the equation B=L+n-1 ? so if I plug in the number of branches and nodes found in the beginning I get 3 loops, I also visually see 3 loops.

what is the symbol representing a circle with an arrow inside ?

2:06 the total number of branches = the total amount of elements in the circuits? i thought there are only 4 branches?

If voltage source is a battery or motor for example, what is the “current source”?

why 5 nodes? Node is a point where 2 or more elements are combined, so in this example it should be 4 nodes.

Although a bit too boomy. It's louder. Try increasing the treble a little

Mic level a little boomy and slightly hot IMO
