    I indescribably appreciate your work such a beautiful simple sat explanation, thank you very much. I just wanted to comment on your last note when you said that if there was no collisions at all the relaxation time would be infinite hence the resistance would be zero, no collisions mean the lowest possible temperature zero kelvin (-273.15 c ), where materials tend to be super conductors, so this taken path of derivation also gives us an elaboration of this phenomenon

    Your speech pattern is like sal's only difference is the voice. And nice explanation of drift velocity.

    Can I use Ohm's Law to find the Voltage (V=IR) ? I mean: I= (V/R) and the substitute and solve for 'V' ?

    sir why elctric field uniform..🙄

    • @carl_johnson_
      @carl_johnson_ 5 месяцев назад +1

      Actually electric fields within a conductor can vary due to impurities, temperature differences, and other factors, but the assumption of a uniform field provides a useful starting point for learning and understanding the basic principles.hope you understood it.

    At the beginning of the explanation, you talked about (E) as a force acting on the electron, but after that (E) became an electric field???

    • @nihilisticalbino
      @nihilisticalbino 6 месяцев назад +1

      The electric field is defined as the force exerted by the electric field over a test charge (a charge so small as to not influence the original charge that creates the electric field in the first place): E = F/q
