Answer 1

Answer on Question #72104-Physics-Electromagnetism

A capacitor has been charged by a dc source. What is the magnitude of the conductance and displacement current when it is fully charged?

Answer

Electric flux through plates of capacitor is

$$\Phi = \frac {q}{\varepsilon_ {0}}$$

$q = const$ when it is fully charged.

Displacement current is

$$I _ {D} = \varepsilon_ {0} \frac {d}{d t} \Phi = \varepsilon_ {0} \frac {d}{d t} \left(\frac {q}{\varepsilon_ {0}}\right) = 0$$

Conductance current is

$$I = C \frac {d V}{d t} = 0.$$
