Fortunately for the user, accurate equivalent circuits may easily be found for capacitors and inductors without iron or ferrite cores. Approximations of other inductive components may also be well described, whose averaged parameters are much better than unknown characteristics.
What is a capacitor and how is It measured?
Capacitance represents the efficiency of charge storage and it is measured in units of Farads (F). The presence of time in the characteristic equation of the capacitor introduces new and exciting behavior of the circuits that contain them. Note that for DC (constant in time) dv signals ( = 0 ) the capacitor acts as an open circuit (i=0).
