    yeah. im pretty confused abt tht. people usually say electrical current
    flows frm + to -, while at the same time acknowledging tht electron flows
    in the opposite direction. how is tht?

    Good video …like the way you deal with one idea at a time ….so many
    teachers jumble up ideas when lecturin …like many music tutors!

    Great, thanks!

    It has to do with OHMs, or the resistance of current along the circuit. A
    light bulb has much more resistance to current than copper wire, and also
    effects the total amount of current that can travel along the entire
    circuit. That’s why without a light bulb, it would short as there is little
    resistance in copper wire and you’d use all your electricity fast.

    Pretty cool!

    Very very slow, but the electric and electromagnetic field will be fast,
    80-90% of C, depending on the conductor. The electric foce can be seen as a
    very hard “cushion” between all the electric charges (electrons, ions).

    @DrJohnCockwalrus so why do we treat photons as particles even though we
    accept the idea of them having no mass and being pure energy? Why dont we
    treat them as waves, and ONLY waves?

  11. kurtasel says:

    why is the electric flow of the battery needs to be reduced like a light
    bulb is needed or there would be a short circuit? is it about the uneven
    voltage (AC voltage)?

  12. Startug says:

    Really good! I love it alot.

    cool post

    You can simplify at 4:41 : 6.24 * 10^18

    great video but 120 volts is not high voltage

  17. icekat83 says:

    Why do batteries run down if all that’s happening is electrons flowing from
    one side to another? And what is it that makes it flow faster or have
    higher voltage? Does anyone have a link suggestion? I will look for other
    vids.

    this video is very good explains the basic concepts of electricity and
    electron flow in a circuit. for someone who wants to understand some
    electricity is very helpful. by: brayan torres

    Can anyone tell me how fast electron moves in a circuit. In one book i
    found, it moves very slow yes almost at dead slow speed (which i agree).
    Other say it move with speed of light which i disagreeeeee :). Also do you
    think higher voltage in circuit moves the electrons faster or slower?

    Cool

  21. WolfVisser1 says:

    A current is measuring the rate the electrons are moving. Currents are
    measured in amps (short for amperes). One amp stands for
    624,0000000000000000, 16 zeros. Hope this helps.

    @Greathoof I wondered the same thing. 🙂 I wonder why the higher version is
    used when the lower version works fine.

  23. jim orr says:

    syedfezu: I agree with you except that an electron can never reach the
    speed of light, the closer it is to the speed of light the greater the
    amount of energy you need to apply. I believe speeds of 99.99999% of spedd
    of light were attained but never the speed of light.

    i soooo agree that the electrons were supposed to move from -ve to +ve i
    mean wat on earth can make ppl think that it can move from +ve to -ve
