    Thanks a lot...
    Your video helped a lot, you assign the sign of the voltage according to the terminal it's leaving, though in the textbook it's where it's starting from.
    The both gives the same answer...
    You helped me understand this, otner videos will just be solving without stating the reason why.
    Thanks.

      Thanks so much for your response and good luck in your academics.
      Where do you watch from?

    In example 1, why is it the V2 negative? the V2 is leaving from the positive terminal, it should be positive, right? please bare with me, I am still learning

    • @zulzyamikaze6663
      @zulzyamikaze6663 ปีที่แล้ว +4

      The current is 9, so the V1 and V2 are -36 and 18, respectively. The sum of the voltage is zero, I think my solution make sense

      also my "i" is 9

      I really get your point, but the correct thing is what has been displayed in the video. Sorry for the late reply

    Hello, why in example one, on resistor number two, is there a minus sign on the right and a plus sign on the left?

    • @SkanCityAcademy_SirJohn
      @SkanCityAcademy_SirJohn  ปีที่แล้ว

      + on a resistor means current leave in that direction and - means current enters from that direction.

      Okay, but then why does the top resistor have a plus sign on the top left? Does the current seem to flow counterclockwise from the resistor? Or the direction of the currents here is chosen arbitrarily

    are the resisitors in series or parallel

    Hello, I think you made a mistake in the first example. I followed through the example and the result of i is 9A not -3A

      Thanks for your contribution , but the right answer is -3A , so please double check your solution
