Question: When a capacitor is charged, the electric field E, and hence the electric flux Φ, between the plates changes. This change in flux induces a magnetic field, according to Ampère''s law as extended by Maxwell: ∮B ⋅dl =μ0(I+ϵ0dΦdt). You will calculate this ...
Introduction to Capacitors, Capacitance and Charge
Introduction to Capacitors – Capacitance The capacitance of a parallel plate capacitor is proportional to the area, A in metres 2 of the smallest of the two plates and inversely proportional to the distance or separation, d (i.e. the dielectric thickness) given in metres between these two conductive plates. ...

Why does capacitance affect the charging time of a capacitor?
If the capacitance is greater, I assume either the area of the capacitor plates is larger or the distance between the plates is smaller. Intuitively, how does the "larger areas" and the "smaller distance between the plates" affect the electrons'' movement and the charge so that it manifests on charging velocity?

6.1.2: Capacitance and Capacitors
Breakdown strength is measured in volts per unit distance, thus, the closer the plates, the less voltage the capacitor can withstand. For example, halving the plate distance doubles the capacitance but also halves its voltage rating. Table 8.2.2 lists the breakdown
