      I get it but I'm still confused lol
      So the current is the same for every single component but another video said current can change in parallel circuits. Idk 💀

    • @Engineer4Free
      @Engineer4Free  ปีที่แล้ว +1

      @@Eduardo_Espinoza The current is not the same in every single component. Two resisters in parallel with difference resistance will have different currents through them, but the same voltage drop across. Check out videos 15-20 for Kirchhoff's laws here: engineer4free.com/circuits as well as videos 21-27 for more examples on current and division.

    One needs not see another lesson on how to calculate complex resistors.

    0:50 - This is the one I was looking for! The formula lol! Even though I already did go through all of these before, forgetting how to calculate and the formula behind it was and will be my biggest problem lol! My memory is not that good enough to recall this one. So watching this part helps me a lot for a forgetful person like me lol! Thanks anyway!

    need help please, how do i know which resistors to combine first? its very confusing because i get different answers depending on the order i combine them

    • @Engineer4Free
      @Engineer4Free  ปีที่แล้ว +2

      There can get not be one right answer. Just take two resistors at a time. Find two that are clearly in series, or two that are clearly in parallel, and apply the appropriate formula. Once they are combined, reassess, and pick two once again. Note that f you have two series resistors that together are in parallel with another one, you must combine the two series ones into their equivalent before doing the parallel calculation. Only the combination of the two would be in parallel with the third, not either if the two originals. Hopefully that makes sense. I'll try to make a few more similar videos in the coming weeeks

    Is there a clear definition of a node ?
    Having some trouble 😕

    • @Engineer4Free
      @Engineer4Free  2 หลายเดือนก่อน +2

      It's basically a region that's electrically common, or has the same voltage potential all over it. So in these videos it would be each wire that is not a resistor, we are assuming these wires to be zero resistance. The elements themselves, like the resistors, have a voltage drop, so they are not part of the nodes. So take a highlighter, and put it on a wire. Then colour along that wire everywhere until it hits a resistor or power source. What you just coloured is one node. Change colours and do it on another wire after to find another. Hope that helps to clarify

    What is equivalent resistence

    • @Engineer4Free
      @Engineer4Free  ปีที่แล้ว +1

      Ohms law says V=IR, or I=V/R, or R=V/I. A battery of a certain voltage will out out a certain amount of current depending on the resistance it feels between its terminals. Turns out that a bunch of resistors arranged in a certain way can give the same overall resistance as a single resistor. If one resistor gives the same overrllal resistance as a bunch of resistors arranged in a certain way, then they give equivalent resistance. This video shows how to simplify find what the single equivalent resistor is to the initial, more complicated configuration. Whether you have the initial more complicated configuration l, or the single equivalent resistor, the battery will feel the same resistance between its terminals and put out the same exact current.
