The current flowing through the capacitor can be ignored
Why does current in an $RC$ circuit become zero when the capacitor
Under constant voltage conditions (cv generator) the current stops because the voltage difference between the generator and the capacitor reaches zero. Under constant current conditions (cc generator) current continues to flow and a spark from the capacitor can be observed, this is dielectric bread-down. This is a standard high school

Capacitors in Circuits: Is Current Ignored?
Current is not ignored in capacitors, but rather it is not the main factor in their function. Capacitors are designed to store electrical energy, and the amount of current flowing through them depends on the voltage and capacitance of the capacitor. So while current is present, it is not the determining factor in a capacitor''s behavior.

6 FAQs about [The current flowing through the capacitor can be ignored]
Is current flowing through a capacitor 0 or 0?
The current flowing in a capacitor is called the charging or discharging current. When a capacitor is connected to a voltage source, it charges and discharges, causing a flow of electric current. 2. Is current through a capacitor 0? No, the current through a capacitor is not always zero.
Does current flow to a capacitor?
Yes, current flows to and from a capacitor. A capacitor is a charge storage element that can store an electric charge. When the capacitor is fully charged, it cannot accept any more charge, and the current flow stops.
What happens when a capacitor is charged?
As a result, the capacitor is charged, which means that there is flow of charge through the source circuit . If a time-varying voltage is applied across the leads of the capacitor, the source experiences an ongoing current due to the charging and discharging cycles of the capacitor.
How does current affect a capacitor?
The current is driven by the potential difference across the capacitor, and this is proportional to the charge on the capacitor, so when the current gets down to 60% of its initial value, that means that the charge on the capacitor has dropped by the same factor.
What happens if a voltage is applied across a capacitor?
If a time-varying voltage is applied across the leads of the capacitor, the source experiences an ongoing current due to the charging and discharging cycles of the capacitor. However, no current actually flows through the dielectric itself.
What happens if a capacitor is connected to a low voltage element?
When a capacitor is connected to a low voltage element, it will emit charges or discharge starts till the voltage of both the elements become the same. Once the capacitor is discharged, the current flow stops to the capacitor because it cannot store more charge when full.
