    This is one of the better explanations that I've seen about this topic. Sometimes one doesn't have to come into direct contact with the electric line to complete the circuit. There have been instances when crane operators have moved the crane boom too near to a line and arcing has occurred.

    Thank you so much for this! My little ones 5 and 7 have been asking me this question for sum time now and FINALLY I get the answer for them :) This was a great and easy to understand video and for that we THANK YOU!! :) :)

    The bird has higher resistance. No internal structures are necessary. That's why you can also see squirrels running across the lines as well.

    I'm not so sure about that,but what i learned in electrical classes is the middle wire on utility poles are the neutural and the top and bottom are the hot wires. so it somewhat make sense that that an arc can not be created because if it sit on any of the 3 wire, it will always be closer to the neutral rathner than the other hot wire.

      YOUR 1ST ANSWER WAS WRONG THAT WAS THE AFFECT, YOUR HEART BEATING HAS NOTHING TO DO WITH COMPLETING A CIRCUT.
      THE 2ND TIME YOU SAID IT CORRECT TOUCHING THE LIVE WIRE & THE GROUND WIRE MAKE YOU A LIKE A SWITCH SO PUT A LIGHT BULB IN YOUR MOUTH AND TOUCH BOTH WIRES. ELECTRIC WIRING 101

    Only at the service box (or fuse box) can the neutral and ground be connected together. Never anywhere else in the building.

    It is not recommended to cut it unless you know what you are doing otherwise it can become just as dangerous with a live loose wire. As for holding it, I would think that it wouldn't affect you that much, maybe a tingle. Sometimes the wires will have rubber covers. Still not recommended. Unless its your job,its not bright to play with live wires :)

  • @simonsmashup

    I know ,in some countries, earth is used as a return path, which means touching both wires on cables does not cause someone to be electrocuted.But this gets me thinking of electric arc. Why doesnt birds get burned if they get near to the cables?Does it depend on resistance of something or simply does birds have some structures to avoid getting shocked? This really confuses me...

  • @edgehead13
    @edgehead13 12 ปีที่แล้ว

    they usually touch the negative and positive wire at the same time. in order to stay safe, you can only hang/sit on ONE of the line

  • @petitio_principii
    @petitio_principii 6 ปีที่แล้ว

    While I had heard that it may be part of the explanation, I thought bird's soles were also significantly less conductive as well. I fail to notice how, without that being significant part of the explanation, the electricity wouldn't just skip people's houses, since, if I'm not very mistaken, they're not connected sequentially, but in parallel. Would that be because the earthing itself is a more of part of the a "larger neutral" than I've always assumed? I'm left with an impression very different than that of the hydraulic model/analogy, where somehow water would just skip filling tubes along the way of a main water circuit, for no reason. I know that with electricity there's that whole thing of it flowing through optimal paths rather than just filling everything, I didn't though it was so optimal.

  • @morganjackson4647
    @morganjackson4647 10 ปีที่แล้ว +1

    what happens when u wanna get down from the power lines.. you would still have to touch the pole to get down.. at that point you would get electricuted because the pole is grounded.. i wouldnt tell kids to do that. they might get shocked on the way on to the power line trying to get next to the birds lol

  • @ladyspeed123

  • @lifemetall
    @lifemetall 8 ปีที่แล้ว

    This is sort of correct. Because nothing is pushing electricity, electricity doesn't really flow, the cables just get charged, if the appliance exmpl is plugged in it starts drawing more amps from the electricity producer, which is the power plant. Doesn't draw voltages, it draws amps, voltage is always there since the sec the cables have electricity

    • @thenakedscientists
      @thenakedscientists 7 ปีที่แล้ว +1

      No, I'm afraid you are wrong. If no electrons are pushed into the cable, how would the "cables just get charged" as you put it? The potential difference really does push electrons into the conductor. I think you are getting confused about whether they need to flow all the way around the circuit to complete the circuit, which they don't.

  • @ravimalik19
    @ravimalik19 7 ปีที่แล้ว +2

    Why do sometimes people get themselves burned e.g. full arm, just hands etc. when they are hanging on a live wire., But the potential is same. Please clear this doubt.

    • @mikevez6639
      @mikevez6639 6 ปีที่แล้ว

      That would only happen if they came into contact with the ground. If you were hanging off a wire and tried to reach the pole with your foot say, then you've connected yourself to ground through the pole and will probably get burned from the current. Although I imagine a wooden pole would be safe once you're not hanging onto thousands of volts!

  • @christofer128

  • @yannitzili8961
    @yannitzili8961 9 ปีที่แล้ว +1

    Pretty but somewhat misleading. It's through the red line that electricity flows into the residential houses. If I'm sitting/hanging on the wire and I have a cut on my skin, or it I'm soaking wet then the current through the live wire (which is a naked uninsulated metallic wire) is very likely to flow through me, everytime sometimes turn their TV on, since I'm practically made out of water and I'm parallel with the wire section I'm sitting on. In any case I will get a good capacitive zap

    • @thenakedscientists
      @thenakedscientists 7 ปีที่แล้ว +1

      No, sorry, you're wrong; there is no potential difference between the different bits of you and the wire because the resistance in the wire is negligible and your resistance, relatively speaking, is huge.

  • @revertedakhi
    @revertedakhi 7 ปีที่แล้ว

    I agree with your explanation abaout how the people or any loving things get electrocuted.. But let me give some additional knowledge on it..human body can touch a live wire using bare hands indeed..but first of all they have to be free from any other objects having directly contact from the ground to avoid line to ground connection simply because your body will serve as a temporary conductor..but you must know you can only do that in a 200-240 volts live wire and live wire alone i repeat...because when you touch it the voltage will drop up to 110v only but never touch a 380 v higher because even if you are free from any ground connected objects ypu will still het eletrocuted due to very high volts..

    • @mikevez6639
      @mikevez6639 6 ปีที่แล้ว

      It depends on the distance you are from objects. Maintenance people touch 500'000 volts wires while they are live, they are just so far from ground that they don't get electrocuted.

  • @TheGiedow
    @TheGiedow 10 ปีที่แล้ว

    If a person would touch a life power cable he might die. Depending on the voltage and the length of the person a current can flow through your body, because there is a magnetic field around the cable which creates a difference in potential. Just look at those videos where workers touch a powerline from a helicopter, there are giant sparks, but the helicopter is not connected to a ground/other powercable.

  • @vineetsaini3065
    @vineetsaini3065 9 ปีที่แล้ว

    Important thing missed is that Bird sitting on main line has high resistance than connecting wire and current always prefer to pass through low resistance.
    So for same power line bird sitting and not get shocked, is disconnected and bird touch both disconnected end each with it leg it will be executed as current in that case only one route through bird body even it has high resistance.

    • @heavychevy2289
      @heavychevy2289 5 ปีที่แล้ว

      It's bonded in your electrical panel it's the first means of disconnect. In a properly designed circuit, if a fault were to occur on the 120-volt outlet between the hot-wire and the ground, the current will flow through ground wire back to the main panel, where it will move to the neutral wire via the neutral-to-ground bond, up to the utility transformer, back down the hot wire to the circuit breaker, tripping the breaker.

      I have question for you since you seem to know about this.
      I live in Norway where we mostly use IT network and in my case with IT network there is 3 twisted cable(s) into to the house which I think are L1, L2 and L3.
      While I was at the attic where power cables comes into the house, I noticed outside birds always seem to stand on these twisted power cables without any problem. In my house we use for example L1 AND L2, L2 and L3 and so on... So I know as fact that there will be closed circuit between live wires if a bird stands on them. So to my question. How is it possible for a bird to do so without problems?

    • @marekfiala7230

      Urbanlion Lion Because the cables are insulated from each other, otherwise it would not be possible to have them twisted. That's why birds can sit on these.

    @hendrikbosmach 7 ปีที่แล้ว

    I don't like your video in which you claim that People can sit hapily on a power line. You haven't heard of a thing called a capacitor? Your body will act like an empty bag that will be filled with charges that are on that powerline, you get charged and during this charging, a current will flow into your body. This all goes very fast so it won't be a long electrocution, but still it will be lethal. A bird is often not electrocuted for two reasons: the first is that they are mostly sitting on the lightning rod, whic is just a grounded cable. The other explenation is that the Voltage isn't really that high, for example above rail tracks. A bird is still a empty bag that will be filled with electrons, but it's way smaller than us. So the current will also be much smaller, sometimes birds will survive this.
    But if a bird hits a 380 kV powerline, it will be killed. No doubt.

    • @hendrikbosmach
      @hendrikbosmach 7 ปีที่แล้ว

      Also a key fact: if you are charged and still not dead, you would have to survive the great journey from that height to the ground.
      And if that didn't kill you, there's always the situation that you're charged by that powerline. When you hit the ground, you'll be de- charged. So again a high current will flow from your body to the ground. Triple lethal it is.
      So don't catch people that fall of a high powerline unless you're not grounded.

Your bed frame is sprung to be connected with continuing waves of power lines, causing electricity fungal diseases.
