Q:这LED筒灯说了个什么意思，亲们1 {0 A6 X2 Q. T( c8 |
A SECTION OF COVER OF THE CORDS IS REMOVED, SO THAT THE COPPER WIRES: [7 r2 J( D; U, z! x; |* T
ARE EXPOSED. THE WIRES ARE COUNTED CAREFULLY, USING A MICROMETER
t$ \ \$ d6 b! J. C l+ YWITH A RESOLUTION OF: 0,001 MM IS USED FOR MEASURE THE DIAMETER OF ALL
2 o8 f% J d- ZCORDS, THEN, THE WIRES DIAMETER IS AVERAGED AND THE RESULT IS USED IN+ `+ @5 b, H( z3 Y
THE FOLLOWING FORMULA TO CALCULATING THE AREA:
* E \2 @. U/ i8 gA = AREA6 n8 Y5 x, ?+ i' h! T7 F! ]6 T
D = AVERAGE DIAMETER7 ]. e8 w! G' K- |5 k
N =NUMBER OF COUNTED WIRES
