    Sir!!!If we connect CC of wattmeter is connect in series with load then what effect on load curret (should increase or decrease or same) if polarity of coil additive or subtractive nature???

    • @calvinjoseph239
      @calvinjoseph239 หลายเดือนก่อน

      The effective current being used for the wattmeter measurement depends on the dot polarity of the current carrying coil and the compensating coil. So the dot polarity determines if the coils are additive or subtractive.

      Node is a point where two or more circuit elements are connected, whereas junction is a point where three or more circuit elements are connected. All junctions are nodes, but not vice versa
