  • Physics Ninja shows you how to setup up Kirchhoff's laws for a multi-loop circuit and solve for the unknown currents. This circuit has multiple voltage sources and cannot be simplified using resistors in parallel and in series.

    My GROOVY Bro... Watching this takes me way...way...way back to high school electronics. They barely had hand-held calculators back then. I barely got through with a "D". I absolutely admire your ability to minipulate those equations I struggled horribly with. The way I'd do it is...set-up the circuit in reality, throw the switch, then jump out the window and wait for whatever battery or resistor blows-up first. (Repeat process 3-times). Increase resistor wattage rating each time.) The Professor.

    Good 'circuit sense' explanations combined with KCL/KVL loop analysis to derive a system of three equations in three unknowns (the three loop currents). Also, good follow through on solving system of equations by substitution for elimination of variables. The bedrock of electrical circuit analysis. Mesh analysis techniques can be easily mastered later with matrix algebra used to solve more complex systems -- kudos for your common sense approach, which I think is very helpful for developing a sense of what's going on in the circuit!

    • @carultch
      @carultch Год назад

      There's also the method of superposition, which simplifies the algebra to plug-and-chug arithmetic, so you don't need to solve a system of equations.
      The way it works:
      1. Pick one of the energy sources of the circuit.
      2. Replace all the other voltage sources with short circuits, and all the other current sources with open circuits, to "turn them off".
      3. Use resistor combinations and voltage dividers to solve for the voltage at a desired point. Identify it with the point and the ID number of the voltage source. Put that aside for later.
      4. Repeat for all the other sources
      5. Add up the voltage at the desired point due to each of the sources, to get the total voltage at that point.
