The circuit board resistance on the various colors of the circle represents what does this mean?: Resistance color ring Meaning: color ring color: black brown red orange yellow green blue purple gray in turn represent 0 1 2 3 4 5 6 7 8 9, four-color ring resistance of the first and second color ring as RMS, the third color Ring for the rate, the fourth channel for the error value;
: Last one：The green part of the circuit board is made of what material, gray it?; Next article：The circuit board, but the shape of the resistance but the cylinder is the resistance of the thing you do, and what is the difference in resistance?
