find your answer please

Explanation:

The capacitor is constructed from two electrically conducting metallic plates separated by an electrically insulating medium. Applying DC voltage on the capacitor no conduction current flows through the capacitor.

The generalised equation for the capacitance of a parallel plate capacitor is given as: C = ε(A/d) where ε represents the absolute permittivity of the dielectric material being used.

The formula which calculates the capacitor current is I= Cdv/dt, where I is the current flowing across the capacitor, C is the capacitance of the capacitor, and dv/dt is the derivative of the voltage across the capacitor.

If there is a voltage difference across the switch the magnitude and frequency of this inrush current can be calculated. The magnitude and frequency of this charging current depends upon the total capacitance and inductance of the circuit as well as magnitude of the applied voltage.
