When measuring by measuring copper access, voltage and current junction junction length measured inCalculate resistivity p=RS/L, which L chooses?.
When the temperature rises to hundreds of degrees Celsius, the quality of copper and iron are unchanged, unchanged on both sides of the force, was mg, but the volume increased, the copper mg increased more than the gravity arm mg arm bar gravity to increase the value of product, product and making the left arm and the arm of force is greater than the right, N will end the upward tilt, a low right high left C. the state.
