  1. You don't know how many times I cried because I couldn't understand all of this, my teacher didn't teach but you saved me thank you so much you made everything so easy and understandable under 15 min is crazy

  2. when i add 2 resistors in series and they arent on the same horizontal line how do i know where to draw the new resistor?
    are there like no wrong answers to where i draw the new combined one i just have to draw it in a smart way so that i can make use instead of putting myself in another loop?

  3. At 6:08, did we only find current going through the 12 ohm resistor because in our initial diagram, we see Io last leaving the 8 ohm resistor? (knowing that the 8 ohm and 4 ohm were combined in series to make the 12 ohm resistor, so Io technically left the 4ohm and 8ohm resistor before combined into one resistor)?

  4. Thankyou for these in-depth and concise videos. At 8:46 you mentioned that 2 ohm, 6 ohm and 18 ohm resistors make a Y. Can we use 2 ohm, 9 ohm, 6 ohm resistors as a delta to be converted to Y? Why or why not?

  5. for the problem at the minute 6, can we also restructure the schematic to the Y one using the node b as the center? I noticed that the way you intuitively assumed the possible resistors in Y formation is by looking at the node where three resistors are connected to while the other ends of each resistor connecting to different nodes. I am sorry if it is confusing. My english is not the best.
