The Coaxial Capacitor with Two Embedded Dielectrics Modern electronic devices are made of certain fundamental building blocks, for example capacitors . Understanding their properties is with respect to their geometrical parameters is of great importance particularly in electrical engineering . To feed our intuition, imagine a parallel plate capacitor similar to the microstrip as shown in the figure below. The equation does not give any exact value of the capacitance per unit length of the microstrip. It however, reveals three important conclusions 1. The capacitance per unit length of a microstrip increases with the increase in trace ... The phasor approach is the easiest imo. You simply let V and I become a phasor. Then you replace all of the differential operators by algebraic expressions. Ive done the capacitor for you . Note: in this form do not forget that both I and V are now phasors and V/I is a complex number ofcourse. The above equation gives you the reactance of a capacitor. To convert this to the impedance of a capacitor, simply use the formula Z = -jX. Reactance is a more straightforward value; it tells you how much resistance a capacitor will have at a certain frequency. Impedance, however, is needed for comprehensive AC circuit analysis.
