FAQs about What current does a capacitor have Image
What happens when a capacitor is charged?
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. As the AC voltage alternates, the current continuously charges and discharges the capacitor, causing it to respond to the changing voltage.
