Current does NOT take the Path of Least Resistance!
Рет қаралды 252,546
Күн бұрынElectric 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.

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.

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.
@BronzeDragon133 2 жыл бұрын
@@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.

Some of these obscure "rules", "laws" etc are just basic common sense disguised behind jargon

Holy smokes this is a cool experiment!! Thanks my Crazy Science Sensei! I'm too much of a wuss to try electronics experiments at home, but I may start...

The setup I had is extremely dangerous with all that exposed metal and wall socket power, but I'm a trained professional. I'd recommend starting with battery powered circuits and hobby bulbs.

Yes, please don't do this with mains electricity. It's far too dangerous even if you know what you are doing. It will work perfectly fine with a battery-powered circuit and will give you exactly the same result. @@ScienceAsylum - Nick, I really wish you had done this with 24V DC - you could have used the same light bulbs, and it would have been far less dangerous.

Saw the title and knew we would be talking about good 'ol Kirchhoff, I still remember learning his current and voltage laws in NFAS back in 2008 and how much people struggled with pronouncing his name lol.

It's interesting, this is one of those things that I've always wondered about. In school they tell you that current takes the path of least resistance; but if that was literally the case; then only one light bulb will light up, in a parallel circuit. I'm really glad to finally have that question answered after all these years. Thank you for such a comprehensive video.

Here's an extra thought. In that circuit, with 4 bulbs in parallel, there is 120V (or so) advertorial that circuit. Each bulb still has 120V across it, regardless of whether or not the other bulbs are present. Each bulb then passes current according only to its own resistance.

Once I posted a negative comment in this section. Well, I am sorry. Now that you have really broadened my mind enough to write it, I must say I appreciate your work a lot. Every time I hear you say sth absolutely wrong, an outward lie, a word trick of some sort, I finish watching a bit off, but some time passes and some things I learn... and a brainwave happens. Always, like in a flash, I remember that you had expressed the same thought that I now produced in my mind and it was me who was on the wrong side of the fence. For that reason, I think this is one of the best channels on the whole Censor-me (because the Medieval is in the vogue) Tube. You do broaden the mind. Good job. Thanks.

when you learn physics, you have thousands of questions, and google doesn't help, there isn't much info, so these visualized explanations are priceless

I love how you explained the divergence in that simple way! It's something that is explained in physics classes, but between the lines because MATH AND FORMALISM FIRST! and necessarily you lost the physical meaning behind it

I got the impression the professors teaching it didn’t have the best understanding. If you watch MIT lectures you will see they know what they are doing and they can explain in the simplest terms.

How can something be so obvious we all already knew and still be totally shocking that it wasn't what we knew at the same time. Nicely done.

Great video Nick. Often hear this misconception, even from some of my electrical engineering buddies. They know Kirchhoff's current law, but I think the path of least resistance "rule" is something they learned so early that they sometimes forget it isn't really true. Next time I have to explain to someone why we need to protect our electronics from lightning, even if we have a lightning rod with a thick cable on it, I will send them your video.

There was an article a while back where a car went off the road. It knocked over a fire hydrant and a streetlight, and stopped over the exposed wires from the streetlight. If I remember right, two people died when they stepped into the water going to help the person in the car. Current was flowing all through that pool, not only the short distance between the exposed wires.
