Current does not flow through a capacitor in the same way as through a resistor. Instead, when a voltage is applied to a capacitor, it charges up by storing energy in an electric field between its plates. This stored energy can then be released when the capacitor discharges.

Why is the charging time of a capacitor lower than the discharging time?
The charging time of a capacitor is usually lower than the discharging time because during charging, the voltage across the capacitor is increasing from zero to its maximum value, which initially allows a higher current to flow. During discharging, the voltage across the capacitor is decreasing from its maximum value to zero, resulting in a lower current flow. This difference in current flow affects the time it takes for the capacitor to charge and discharge.
When a capacitor is being discharged in which direction does positive charge flow?
The 'conventional current' flows out of the positive side of the charged capacitor, and into the negative side. However, even though we never talk about it, we know that the things that actually carry the physical current around are the negatively charged electrons, and we know that when a capacitor is discharging, the electrons are flowing out of the negative side and into the positive side.
Is it true that an alternating current passing through a capacitor While a direct current can not Explain?
Yes, it is true that an alternating current can pass through a capacitor, as capacitors allow AC to flow through them due to their ability to store and release electrical energy in response to voltage changes. In contrast, a direct current cannot pass through a capacitor because the capacitor blocks the steady flow of DC by charging up and reaching a voltage equilibrium.
Can dc current pass through capacitor which is in series connection?
DC current cannot pass through a capacitor in series connection in the long run because the capacitor charges up and blocks DC current. Initially, there might be some current flow until the capacitor charges, but once it is fully charged, no current will flow through the capacitor.
What is the difference between a resistance and a capacitor?
A resistor is a passive two-terminal electrical component that limits or controls the flow of current in a circuit, while a capacitor is a passive two-terminal electronic component that stores and releases electrical energy. Resistors dissipate energy in the form of heat, whereas capacitors store energy in an electric field.
How does an ac curcuit work if current cant flow through a capacitor?
AC current can flow through a capacitor, it's DC current that can't
Did capacitor allow change in current?
capacitors allow ac current to flow.
A W pf capacitor is connected into a 240 V Hz circuit. what is the current flow in this circuit?
a 30 pf capacitor is connected into a 240v, 60 hz circuit. what is the current flow into the circuit
What current does a capacitor pass?
ac power (alternating current) it blocks dc power Many people will say a capacitor can't pass current because they consider Electric current to be the flow of electrons but that's not necessarily the case. In a capacitor current is passed by the building up and dropping of an electric field. DC does not flow for long of course.
What is the function of mylar capacitor?
In electronic circuits a capacitor is used to pass AC and block DC.
Charge buildup between the plates of a capacitor stops when?
Charge buildup between the plates of a capacitor stops when the current flow through the capacitor goes to zero.
What happens to current flow in a capacitive when the DC voltage across the capacitor is approximately equal to the source voltage?
As long as you don't exceed the breakdown voltage of the capacitor ... which is marked right on it ... DC voltage on it produces NO current flow through it. Only AC 'appears' to flow through a capacitor, and even that appearance is bogus when you really get down to it.
Does the alternative current flow through capacitor?
Yes. Voltage is shifted 120 degrees.
What would happen to the current flow in a dc circuit when the capacitor is fully charged?
A capacitor charge as a time constant of R resistance C capacitance in ufd and it is defined as 63% for one time constant for the constant voltage source. Electronic engineers assume that a capacitor is fully charged by a 5 times constant. however mathematically speaking it will never be fully charged for obvious reasons. Therefore the answer is current will never stop/
Why does DC not flow through a capacitor?
Actually, neither d.c. nor a.c. current passes through a capacitor. A.C. current 'appears' to flow through a capacitor but, in reality, it is only flowing through the connecting circuit while what is known as a 'displacement current' (actually, a distortion of the atoms' shells rather than a conduction current) occurs within the dielectric separating the capacitor's plates. D.C. current is 'blocked' by a capacitor because, when the capacitor is fully charged, the potential difference appearing across its plates is equal and opposite that of the supply. With no net potential difference in the circuit, no current can flow.
What to expect if a resistor is placed in a dc circuit with a capacitor?
when we replace the resistor with a capacitor ,the current will flow until the capacitor charge when capacitor will fully charged there is no current through the circuit because now capacitor will act like an open circuit. for more info plz E-mailt me at "zaib.zafar@yahoo.com"
Does a capacitor store energy in form of an magnetic field?
Current stops going into a capacitor when it's voltage is equal to the supply voltage. From then there is no flow of current, so there is no magnetic field. Yet the capacitor remains charged and has energy to release if required.
