The mathematical area in origin represents the area of the algebraic sum of trapezoids. Whereas the absolute area is the sum of absolute trapezoid values.
For area under the curve (in CV, which sweeps the positive and negative current, during forward and reverse scan) you have to consider the following facts...
If you use (Option 1) Mathematical area, which is nothing but the algebraic sum of the trapezoids, what ever the negative current you are getting will be subtracted from the positive current (or vice versa)... Hence you will be having the difference in the positive and negative values of area [If both sides of the axis is same you will have "ZERO" as a result... .
If you use (Option 2) Absolute area, which is the sum absolute trapezoid values, you will lose nothing. Hence you will get the absolute value of the area under the curve...
Hence abs area gives the original value of the area under curve |
