Customer Service9. CHARGING A CAPACITOR At first, it is easy to store charge in the capacitor. As more charge is stored on the plates of the capacitor, it becomes increasingly difficult to place additional charge on the plates. Coulombic repulsion from the charge already on the plates creates an opposing force to limit the addition of more charge on the plates. Voltage across a
Customer ServiceWhen a capacitor is discharging (when there is no battery linked to it), it almost acts like a battery. It will start giving off its energy (which is limited, unlike a battery). When the capacitor is linked to a battery, it will store energy. When it''s fully charged it will behave like an open switch. Exam Tip. The direction of the current for discharging is opposite to the direction for
Customer ServiceWhen a capacitor is either charged or discharged through resistance, it requires a specific amount of time to get fully charged or fully discharged. That''s the reason, voltages found across a capacitor do not change immediately (because charge requires a specific time for movement from one point to another point). The rate at which a
Customer ServiceAs more charge is stored on the capacitor, so the gradient (and therefore the current) drops, until the capacitor is fully charged and the gradient is zero. As the capacitor discharges (Figure 3(b)), the amount of charge is initially at a maximum, as is the gradient (or current).
Customer ServiceAs a capacitor charges, electrons are pulled from the positive plate and pushed onto the negative plate by the battery that is doing the charging. Looking just at the negative plate, note that electrons repel each other, so they will spread out evenly on the negative plate as they accumulate. Since electrons repel each other, as more electrons

Customer ServiceCharging and discharging a capacitor. When a capacitor is charged by connecting it directly to a power supply, there is very little resistance in the circuit and the capacitor seems to charge instantaneously.

energy dissipated in charging a capacitorSome energy is s ent by the source in charging a capacitor. A part of it is dissipated in the circuit and the rema ning energy is stored up in the capacitor.

While during the discharging of the capacitor, current flows away from the positive and towards the negative plate, in the opposite direction. Q2. Is the Time for Charging and Discharging of the Capacitor is Equal?
Discharging a Capacitor A circuit with a charged capacitor has an electric fringe field inside the wire. This field creates an electron current. The electron current will move opposite the direction of the electric field. However, so long as the electron current is running, the capacitor is being discharged.
It happens when the voltage is placed across the capacitor and the potential cannot rise to the applied value instantaneously. As the charge on the terminals gets accumulated to its final value, it tends to repel the addition of further charge accumulation.
Consider a circuit having a capacitance C and a resistance R which are joined in series with a battery of emf ε through a Morse key K, as shown in the figure.
