RESOURCES > EIS > CPE > CALCULATING C > CALCULATOR This calculator can be used to calculate the "true" capacitance from a depressed semicircle model ( a Constant Phase Element in parallel with a resistor ). If your data has been fit to a depressed semicircle, locate the frequency at the top of the semicircle, and enter omega_{max}, Qo, and the exponent, n. Press [Convert...] to update the value of the capacitance.

The equation for the constant phase element assumed by this calculator is: Z = 1 / [ Qo * ( j * )^{n} ] More
