Which of the following depends on charging and discharging of capacitor?

Which of the following depends on charging and discharging rate of a capacitor? Explanation: The time constant in a circuit consisting of a capacitor is the product of the resistance and the capacitance. Smaller the time constant, faster is the charging and discharging rate and vice versa.

What is the charging and discharging of capacitor?

When a Capacitor is connected to a circuit with Direct Current (DC) source, two processes, which are called "charging" and "discharging" the Capacitor, will happen in specific conditions. In Figure 3, the Capacitor is connected to the DC Power Supply and Current flows through the circuit.

What do capacitors depend on?

There are three factors which influence capacitance: the size of the conductors, the size of the gap between them, and the material between them (the dielectric). The bigger the conductors, the bigger the capacitance. The smaller the gap, the bigger the capacitance.

What is the main objective of charging and discharging a capacitor?

OBJECTIVE: The objective of this experiment is the study of charging and discharging of a capacitor by measuring the potential difference (voltage) across the capacitor as a function of time. From this measurement the student will use the Logger Pro software to calculate the charge and the current as functions of time.

What is the conclusion for charging and discharging of capacitor?

Conclusion : No current flows through the dielectric during the charging and discharging phase except leakage current. It takes 5 times constant to charge or discharge a capacitor even if it is already somewhat charged.

Capacitor charging and discharging

What happens to the charge in a capacitor during discharging process?

the discharging current decreases from an initial value of to zero. the potential difference across the capacitor plates decreases from to zero, when the capacitor is fully discharged. the potential difference across the capacitor is always equal to the potential difference across the resistor.

Does capacitance depend on charge?

The capacitance for a given capacitor will strictly be a constant. Capacitance does not depend on the voltage of the charging source or the charges of the plates. Capacitance depends only on the physical characteristics of the capacitor like the area of the plates and the distance between the plates.

Is capacitance dependent on material?

The capacitance depends on the geometry of the capacitor and on the material between the plates.

What causes a capacitor to discharge?

What causes a capacitor to discharge? When the capacitor is fully charged and the electrical field from the source surrounding the capacitor goes down to zero, it causes an electron flow from the conductive plates of a capacitor to the circuit, which then causes the capacitor to discharge.

Which of the following factors determine the capacitance of a capacitor?

The three factors which affect the capacitance of a parallel-plate capacitor are the area of the plates, the distance apart of the plates and the nature of the insulating material or dielectric between them. These factors may be investigated by the following experiments.

Which of the following factors does not affect the capacitance of a capacitor?

The curvature of the plates means the plate is spherical plates or the cylindrical plates. So, that the type of the material of the plates is the only factor that does not affect the capacitance of the capacitor.

Does capacitance depend on thickness of plates?

What does affect capacitance is the thickness of the dielectric, so the thinner the better, but it must be thick enough to block/handle the rated voltage. More metal (and dielectric) in terms of windings also increases capacitance.

Is the time for charging and discharging of capacitor the same?

A capacitor doesn't charge or discharge at the same rate as time goes on. The voltage across the capacitor follows a “natural” pattern over time until the capacitor is fully charged or discharged.

What is discharging of capacitor?

If the plates of a charged capacitor are connected through a conducting wire, the capacitor gets discharged. Again there is a flow of charge through the wires and hence there is a current. q=QeCR−t.

How does the charging and discharging currents change over time?

Since the value of the resistor does not change, then the current through it must begin to decrease. After some period of time, the current will decline to zero and the voltage across the capacitor will rise to equal that at the battery.

How does capacitance of capacitor depends on charge and potential difference?

We have capacitance , C=Q/V , where Q= charge on capacitor , V= potential difference across the plates , when the potential difference V is increased , charge on capacitors also increases such that the ratio Q/V , remains constant i.e. capacitance remains constant .

Does charge depend on voltage?

It appears that OP is confused about the voltage powered by a battery and the electric potential (voltage) due to a system of charges which depends just on charges and distances. The voltage developed across a cell's terminals depends on the energy release of the chemical reactions of its electrodes and electrolyte1.

Does the capacitance depend on the value of charge Q or V?

The amount of charge that moves into the plates depends upon the capacitance and the applied voltage according to the formula Q=CV, where Q is the charge in Coulombs, C is the capacitance in Farads, and V is the potential difference between the plates in volts.

Does the capacitance of a capacitor depend on the voltage applied on it?

A capacitor is a device that stores an electrical charge and electrical energy. The amount of charge a vacuum capacitor can store depends on two major factors: the voltage applied and the capacitor's physical characteristics, such as its size and geometry.

Is capacitance dependent on distance?

Capacitance is directly proportional to the electrostatic force field between the plates. This field is stronger when the plates are closer together. Therefore, as the distance between the plates decreases, capacitance increases.

Which among the following expressions relate charge voltage and capacitance of a capacitor?

1. Which among the following expressions relate charge, voltage and capacitance of a capacitor? Explanation: Q is directly proportional to V. The constant of proportionality in this case is C, that is, the capacitance.

How does resistance affect capacitor discharge?

Resistance reduces the current which can flow through a circuit so the rate at which the charge flows will be reduced with a higher resistance. This means increasing the resistance will increase the time for the capacitor to charge or discharge.

What are three factors that affect the capacitance of a capacitor?

The capacitance of a capacitor is affected by the area of the plates, the distance between the plates, and the ability of the dielectric to support electrostatic forces.

How does the charge affect the capacitance of a capacitor?

When a capacitor is fully charged there is a potential difference, (p.d.) between its plates, and the larger the area of the plates and/or the smaller the distance between them (known as separation) the greater will be the charge that the capacitor can hold and the greater will be its Capacitance.
