When a capacitor charges, current flows into the plates, increasing the voltage across them. Initially, the current is highest because the capacitor starts with no charge. As the voltage rises, the current gradually decreases, and the capacitor approaches its full charge.
How does a capacitor work in an AC circuit?
In AC circuits, current through a capacitor behaves differently than in DC circuits.

What is a negative capacitance?
The capacitor is a key element of electronic devices and is characterized by positive capacitance.

Capacitor voltage division principle diagram
But just like resistive circuits, a capacitive voltage divider network is not affected by changes in the supply frequency even though they use capacitors, which are reactive elements, as each capacitor in the series chain is affected equally by changes in supply frequency. This ability of a capacitor to oppose or react against current flow by storing charge on its plates is called reactance, and as this reactance relates to a capacitor it is therefore. When a fully discharged capacitor is connected across a DC supply such as a battery or power supply, the reactance of the capacitor is initially extremely low and maximum circuit current. Capacitance, however is not the only factor that determines capacitive reactance. If the applied alternating current is at a low frequency, the reactance has more time to build-up for a given RC time constant. Now if we connect the capacitor to an AC (alternating current) supply which is continually reversing polarity, the effect on the capacitor is that its.
