Abstract

 

We describe a method for the exact data linearization of the charging curve of a capacitor. The calculations required are as simple as those involved in the linearization of the discharging curve, allowing analysis of the charging process using the graphical and fitting tools available in introductory physics courses. The proposed method can also be generalized to university-level problems involving biased exponential curves as an input parameter estimation method for nonlinear data fitting procedures.
