How does current flow in a circuit with a capacitor?
When a capacitor is connected to a battery, current starts flowing in a circuit which charges the capacitor until the voltage between plates becomes equal to the voltage of the battery.
Why doesn''t voltage drop to 0 when a capacitor becomes fully charged
My question: From the beginning of charging to when the capacitor is fully charged, current will gradually drop from its starting rate to 0 because, like I previously explained, the atoms on negatively charged plate will be able to accept less and less electrons as each individual atom''s valence orbit reaches its maximum capacity.
Capacitor charge and Discharge
The shape of the discharging graph is an exponential decay, meaning that the rate of decay of the charge (or the gradient or the current) depends on the amount of charge stored at any given time. For a discharging capacitor, the current is directly proportional to the amount of charge stored on the capacitor at time t.

Why does DC current pass initially through a capacitor while it is
No conduction current flows through a capacitor except for a tiny leakage current. What you are seeing is charge flowing onto one plate and off of the other plate giving the illusion that charge (current) is passing through the capacitor between the plates.
RC Charging Circuit Tutorial & RC Time Constant
No, as explained in the tutorial. At time: t = 0, the capacitor (C) is not charged, so there is no capacitor voltage (Vc) to oppose the flow of current. Then the entire supply voltage Vs is dropped across the resistor (R) with the maximum instantaneous circuit current (i) at t = 0, given as: i = Vs/R, since Vc = 0V.
When capacitor is fully charged.
A capacitor is fully charged when it cannot hold any more energy without being damaged and it is fully discharged if it is brought back to 0 volts DC across its terminals.You can also think of it as the capacitor loses its charge, its voltage is dropping and so the electric field applied on the electrons decreases, and there is less force pushing the remaining electrons

Can a capacitor be charged in an open circuit? No, a capacitor cannot be charged in an open circuit. As mentioned earlier, a closed loop is needed for current to flow and charge the capacitor. Without a closed circuit, there is no path for the electrons to move and the capacitor will not become charged.
RC Charging Circuit Tutorial & RC Time Constant
When an increasing DC voltage is applied to a discharged Capacitor, the capacitor draws what is called a "charging current" and "charges up". When this voltage is reduced, the capacitor begins to discharge in the opposite direction.
6 FAQs about [Is there any current when the capacitor is not charged ]
What happens if a capacitor is fully charged?
Hence, a fully charged capacitor blocks the flow of DC current. There is only a transfer of electrons from one plate to the other through the external circuit. The current does not flow in between the plates of the capacitor. When a capacitor is charged, the two plates carry equal and opposite charge.
Does a capacitor have an electric charge?
Well though there is no electric charge flowing between the plates of the capacitor, there is the infamous displacement current, that is a "virtual" current that corresponds to the rate of change of electric field between the plates of the capacitors as the capacitor is charging.
What happens when a capacitor voltage equals a battery voltage?
When the capacitor voltage equals the battery voltage, there is no potential difference, the current stops flowing, and the capacitor is fully charged. If the voltage increases, further migration of electrons from the positive to negative plate results in a greater charge and a higher voltage across the capacitor. Image used courtesy of Adobe Stock
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.
Why does a fully charged capacitor block the flow of DC current?
When a DC voltage is applied across a capacitor, a charging current will flow until the capacitor is fully charged when the current is stopped. This charging process will take place in a very short time, a fraction of a second. Hence, a fully charged capacitor blocks the flow of DC current.
How does a fully charged capacitor work?
This charging process will take place in a very short time, a fraction of a second. Hence, a fully charged capacitor blocks the flow of DC current. There is only a transfer of electrons from one plate to the other through the external circuit.
