How do capacitors work?
What is a capacitor? Take two electrical conductors (things that let electricity flow through them) and separate them with an insulator (a material that doesn''t let electricity flow very well) and you make a capacitor: something that can store electrical energy.Adding electrical energy to a capacitor is called charging; releasing the energy …
How much current does a capacitor draw when charging?
$begingroup$ It has 2 components, when initially turned ON, inrush current exists, which depends on ESR of your cap and dV/dT of turn ON. after that transient event, capacitor slowly charges.

Why does DC current pass initially through a capacitor while it is ...
Even for an ac current, no conduction current passes through the capacitor. In the case of ac current (charge) is flowing on to and off of the two plates via the wires on either side of the capacitor in a repetitive fashion. However you will often see it mistakenly and confusingly stated that ac current flows "through" a capacitor

Capacitors and Calculus | Capacitors | Electronics Textbook
Capacitors do not have a stable "resistance" as conductors do. However, there is a definite mathematical relationship between voltage and current for a capacitor, as follows:. The lower-case letter "i" symbolizes instantaneous current, which means the amount of current at a specific point in time. This stands in contrast to constant current or average current …

When the voltage reaches a threshold value, a current flows through the lamp that dramatically reduces its resistance, and the capacitor discharges through the lamp as if the battery and charging resistor were not there. Once discharged, the process starts again, with the flash period determined by the (RC) constant (tau).
What is the formula for charging a capacitor with constant current?
$begingroup$ To achieve a constant current through a capacitor implies that the voltage across the capacitor increases without limit. In reality, "without limit" is limited by the capacitor exploding. 5 tau is generally taken to be "good enough" at 99.3% charged. $endgroup$ –
Capacitance and Charge on a Capacitors Plates
The current that flows through a capacitor is directly related to the charge on the plates as current is the rate of flow of charge with respect to time.
