Measuring an EIS spectrum takes time (often many hours). The system being measured must be at a steady state throughout the time required to measure the EIS spectrum. A common… read more →
Electrical circuit theory distinguishes between linear and non-linear systems (circuits). Impedance analysis of linear circuits is much easier than analysis of non-linear ones. The following definition of a linear system… read more →
EIS data are commonly analyzed by fitting them to a model of an equivalent electrical circuit. Most of the circuit components in the model are common electrical elements such as… read more →
Almost everyone knows about the concept of electrical resistance. Resistance is the ability of a circuit element to resist the flow of electrical current. Ohm’s law defines resistance in terms… read more →
