Question

the conventional current flowing onto the plates of a capacitor decreases as the capacitor charges. during this time, the displacement current associated with the capacitor

remains constant.
decreases.
does not exist.
increases.

Explanation:

According to Maxwell's equations, the displacement current \(I_d=\epsilon_0\frac{d\Phi_E}{d t}\), and for a capacitor in a circuit, the conduction current \(I_c\) (conventional current) and the displacement current \(I_d\) are related by \(I_c = I_d\). When the conventional current \(I_c\) flowing onto the plates of a capacitor decreases as the capacitor charges, since \(I_d = I_c\), the displacement current \(I_d\) also decreases.

Answer:

decreases.
