WebCharge is measured in coulombs, C. The charge of an electron is 1.6 x 10-19 C. In other words, it takes 6,250,000,000,000,000,000 electrons to make up 1 coulomb of charge. Webwhere the parameter a is the height of the curve’s peak, b is the position of the center of the peak; and c = 2σ 2 (where σ is the standard deviation) controls the width of the curve. Taking the logarithm on both sides of Equation (4), it becomes: (5) where A2 = −1/ c2, A1 = 2 b / c2, A0 = ln a − b 2 / c2.
