Capacitors do not so much resist current; it is more productive to think in terms of them reacting to it. The current through a capacitor is equal to the capacitance times the rate of change of the capacitor voltage with respect to time (i.e., its slope).
The current through a capacitor is equal to the capacitance times the rate of change of the capacitor voltage with respect to time (i.e., its slope). That is, the value of the voltage is not important, but rather how quickly the voltage is changing. Given a fixed voltage, the capacitor current is zero and thus the capacitor behaves like an open.
W W is the energy in joules, C C is the capacitance in farads, V V is the voltage in volts. The basic capacitor consists of two conducting plates separated by an insulator, or dielectric. This material can be air or made from a variety of different materials such as plastics and ceramics.
An ideal capacitor is characterized by a constant capacitance C, in farads in the SI system of units, defined as the ratio of the positive or negative charge Q on each conductor to the voltage V between them: A capacitance of one farad (F) means that one coulomb of charge on each conductor causes a voltage of one volt across the device.
Paper and plastic film capacitors usually have insulation resistance values ranging from 6000 to 12000 MΩ. This is not quite explicit because the x C is also used to measure the quality of the insulation. gives the time in seconds during which the voltage between the terminating wires of a charged capacitor decreases to 37% due to self-discharging.
Equation 6.1.2.6 6.1.2.6 provides considerable insight into the behavior of capacitors. As just noted, if a capacitor is driven by a fixed current source, the voltage across it rises at the constant rate of i/C i / C. There is a limit to how quickly the voltage across the capacitor can change.

Capacitors | Brilliant Math & Science Wiki
2 · Capacitors are physical objects typically composed of two electrical conductors that store energy in the electric field between the conductors. Capacitors are characterized by how much charge and therefore how much electrical energy they are able to store at a fixed voltage. Quantitatively, the energy stored at a fixed voltage is captured by a quantity called capacitance …
