      anuj singh thats all about conventional current .. in reality
      -ve pole of battery is higher potential & +ve pole is lower but we consider the +ve as higher and -ve as lower !
      So according to reality electrons at power house have high potential as compared to earth !

    sir can we define 1 ohm resistance as :
    1 ohm is that resistace when 47 Ampere of current is developed when potential difference of 47 volt is applied accross.
    becase R=V/I => R=47/47 => R=1.😅🤔

    • @abhishekmohanty232
      @abhishekmohanty232 7 лет назад +1

      so it means that the more appropriate definition of 1 ohms should be:
      1 ohm is that resistance when 'X' Ampere of current is developed when the potential difference of 'X' volt is applied across.
      because R=V/I => R=X/X => R=1.
