Reduction of real systems to equivalent RLC passive networks is an essential description tool used in electrical engineering to construct electrical networks whose properties mimic the real system exactly. In general sense, an electrochemical system is merely an impedance to a perturbing electrical signal with a small amplitude. The electrical behavior of an interface can be therefore represented by an electrical equivalent circuit, a circuit of resistors and capacitors (inductances are usually not used) that pass current with the same amplitude and phase as the real system would under the same excitation. A proper design of an equivalent circuit is very important step in the evaluation procedure. The actual impedance measurement than confirms or refutes the circuit.
