Current does NOT take the Path of Least Resistance!

  • Electric current has to obey certain rules, like taking the path of least resistance. But when rules are that simple, they tend to be a little wrong. Let's see if we can write a better one.

      The equivilent resistance of loads in parallel being less does feel a bit counter intuitive.
      However, as resistance gets smaller, then the system draws more current. So, the whole system having less resistance, and the drawing more current than a single element does make sense.

      @@corydiehl764 , alternatively, think about it more intuitively in terms of _conductance,_ which is the reciprocal of resistance. When you have parallel paths, each with some conductance, the overall conductance is just the sum of the individual conductances, because any of the paths can be taken. It's the same as if you combined all of the paths into a single path. Ultimately, that's why 1/R = Σᵢ (1/Rᵢ).

    I became an EE specifically because my high school teachers failed to explain exactly this concept properly. I remember asking my science teacher "if electricity follows the path of least resistance, then why is it dangerous to touch a power line with a ladder? Shouldn't It all flow through the low resistance ladder?". He basically shrugged his shoulders and said he didn't know.
    It wasn't until well into my second year that it all finally clicked and I recognized all the misconceptions I'd learned. It's hard to shake poorly learned concepts out of your head. I still encounter journeyman electricians who don't properly understand Kirchoffs' or Ohm's laws.

    The conclusion would be that yes, current takes the path of least resistance, but that doesn’t imply it takes *only* the path of least resistance (which is the impression the phrase gives).
    As an additional side note, there’s a circuit known as a “current divider” which shows that in resistors (and impedances in AC circuits) connected in parallel, the current of the source flows through *all* resistors, not just through the smallest resistance. Furthermore it shows the current through any resistor is inversely proportional to its resistance, what we’d expect from Ohm’s law. The only time where the current would only flow through the path of least resistance is if such resistance is exactly 0 ohms (an ideal wire).
    -
    The short description of the del operator you gave was clever!
    And the explanation of the equation of conservation of charge was excellent. Electromagnetic theory was quite difficult for me and my friends since equations aren’t always explained in depth, only their proof/derivation is shown.
    The assumption about KCL is hardly ever stated and people end up think it is always valid. Thanks for pointing that out! In transmission lines, current going in doesn’t equal current going out.
    -
    Side note 2: the video is too good and it covers more than just correcting “path of least resistance”. Maybe you could change it to “Current does NOT take the path of least resistance | When KCL is not true” or something like that 🤔

    I always laughed at that. When I design even a simple circuit, it takes ALL paths...inversely proportional to resistance. If it didn't, your house would only have one light or appliance working at any one time...assuming it was the one with the lowest resistance in the power block. And the lowest power block resistance in the entire circuit of the power plant...

      An average of all paths is seen by the battery. But a dead short would put all the lights out, each path must have resistance for it to work. An old model railroad trick, put a car tail light bulb in series with the track. If something metal falls on the track and shorts it out, the bulb will light up, and prevent a dead short. It barely lights at all while the train is running.

      @@alphagt62 Even a dead short keeps all paths powered--it's just that the short is of extremely low resistance. Usually it draws more power than the source can easily supply, leaving little for alternate paths and the voltage sags severely. In a perfect world, with a perfect supply, the lights/devices would stay on. But that dead short would get very, very hot...

    I really love that you show the formulas and explain what they say. Not being able to read (comprehend) formulas seems to be one of the biggest hurdles in scientific literacy. People seriously under-estimate how easier can your everyday life be, if you know how to read, use and design scientific formulas + apply some basic algebra to them. If you reach the level of being able to enter formulas into excel, you can calculate pretty much anything that doesn't involve landing people on the moon.
    It's one of the trickiest skills to teach. Children don't wanna learn it, because it's useless for problems they are facing in their daily lives. Adults don't wanna learn it, because they are settled in using math-less heuristic/intuitive approaches to solve their problems. You should see the utter horror and confusion in people's faces, when you suggest calculating the solution to a complex problem instead of guesstimating it.

But the current ripples in the illustration show electron flow or current flow moving in the direction from positive to negative. It’s the other way around. Well, you did mention charge flow a few times, and that would suffice in engineering circles, but this lesson targets basic electronics students. Thanks for the math lesson, though.
