Typical capacitor plates are made of conductors (metals) which have a huge number of charge carriers. Consider that (very roughly) \$N_A = 6×10^{23}\$, while \$C = 6×10^{18}e\$, so 1 mol of metal has...

Many practical capacitors have very weak dependence on the conductor material. Capacitor Equivalent Series Resistance (ESR) will be affected by plate material and thickness/routing and is a significant...

In a typical capacitor, charges will be concentrated in thin layers on the portions of each electrode that are nearest the oppositely-charged electrode. Although this layer essentially always has...

To the best of my knowledge the chose of material DOES matter - even for the static case. If not it would imply that most insulators could be used as electrode as well due to the residual chance of...

The active part of a capacitor is the dielectric. That's where the energy is stored, that's what the voltage is developed across. The plates just transport current to the right places. A high...

It's the same for an inductor - the value of inductance remains constant irrespective of the wire's conductivity. Take it to extremes and consider the speed of radio waves and how they propagate...

Yes that is true, capacitance is:\$C = \frac q V\$where q is the charge and V the voltage between the plates.As long as the charge \$q\$ can be "hold in place" this relation applies. I mean, there is...

As a student, learning about a capacitor after understanding what a resistor is, it was quite surprising to note that the capacitance does not depend on the nature of the plates used, at least in any...
