    All examples shown have the load at the end of the circuit length.
    In a circuit with fixed loads such as a lighting radial, the loads are at different points/lengths from the CU.Does this mean we have to calculate vd at each individual point and add the sum?
    Lastly in a domestic situation its unlikely all lights will be on at the same time. are there any diversity calculations to account for or do we always assume worst case?

    • @learnelectrics4402
      @learnelectrics4402  2 หลายเดือนก่อน

      Diversity says use 66% of the total possible load for domestic lighting.
      With domestic lighting, which isn't that long a length and is comparatively lightly loaded, especially with today's low energy lamps, I never worry about distributed loads.
      Industrially, where the loads can be high and the distances long, then yes, I would calculate for each point of use.
      Thanks for watching. Dave.

    At 4:08 the total watts is 1,646 and not 2,215 (lower cable resistance, and thus lower overall resistance, should increase the total power).

    Thanks for the video. Very clear as usual (small typo in table though - I= V /I - instead of I=V/R)

    • @learnelectrics4402
      @learnelectrics4402  ปีที่แล้ว +1

      Yep, it seems that everyone spotted that. Corrected on that and repeated slides. Glad someone is checking for me, really appreciated, it helps, Dave,

    It seems that there is a typo mistake
    Thanks

      UK, Great Britain, but learning about electrics helps with any electrical circuit. Just adapt to your own needs. Hope this helps.

    Hi Dave ,Thank you for clear easy instructions.Dave just to let you know I think there is a typing error in your two initial tables. We see I=V÷I instead of I=V÷R..YOUR LECTURES ARE FANTASTIC.

    • @learnelectrics4402
      @learnelectrics4402  ปีที่แล้ว

      Yes, my typo. Everyone seems to have spotted that except me. Thanks for the feedback, it is appreciated, Dave.

    Correction Davo.
    At 4.17.
    I = V/R. As you know

    • @learnelectrics4402
      @learnelectrics4402  ปีที่แล้ว +1

      Wow, that's some super typo. Thanks for that, corrected on that and other slides. Hopefully folk will see through it. That's what I love about you guys, you never let me get away with anything - it keeps me on my toes.
      Thanks again, really appreciated, Dave.

    If you don't understand voltage drop from this video, don't worry, plumbing is still waiting for you!🤣😂😇
