This process of depositing charge on the plates is referred to as charging the capacitor. For example, considering the circuit in Figure 8.2.13, we see a current source feeding a single capacitor. If we were to plot the capacitor''s voltage over time, we would see something like the graph of Figure 8.2.14 .
Capacitors | Brilliant Math & Science Wiki
4 · Capacitors are physical objects typically composed of two electrical conductors that store energy in the electric field between the conductors. Capacitors are characterized by how much charge and therefore how much electrical energy they are able to store at a fixed voltage. Quantitatively, the energy stored at a fixed voltage is captured by a quantity …

8.4: Energy Stored in a Capacitor
As the capacitor is being charged, the charge gradually builds up on its plates, and after some time, it reaches the value Q. To move an infinitesimal charge dq from the negative plate to the positive plate (from a lower to a higher potential), the amount of work dW that must be done on dq is (dW = W, dq = frac{q}{C} dq).

Capacitance, Charging and Discharging of a Capacitor
Capacitance Capacitance of a capacitor is defined as the ability of a capacitor to store the maximum electrical charge (Q) in its body. Here the charge is stored in the form of electrostatic energy. The capacitance is measured in the basicSI units i.e. Farads. These ...

Charging and Discharging of a Capacitor, RC Circuits
The time taken to charge it to 63% of the maximum charge is called the time constant of the capacitor. It is equal to the product of capacitance and resistance. If the value of the capacitance and resistance is large, the time constant is large enough to be measurable easily without the use of sophisticated instruments.
Physics A level revision resource: Introduction to capacitors
Unlike the battery, a capacitor is a circuit component that temporarily stores electrical energy through distributing charged particles on (generally two) plates to create a potential difference. A capacitor can take a shorter time than a battery to charge up and it can release all the energy very quickly.

18.5 Capacitors and Dielectrics
The equation C = Q / V C = Q / V makes sense: A parallel-plate capacitor (like the one shown in Figure 18.28) the size of a football field could hold a lot of charge without requiring too much work per unit charge to push the charge into the capacitor.
How do capacitors work?
A capacitor attached to the flash gun charges up for a few seconds using energy from your camera''s batteries. (It takes time to charge a capacitor and that''s why you typically have to wait a little while.) Once the capacitor is fully charged, it …
