When you use a flash camera, it takes a few seconds to charge the capacitor that powers the flash. The light flash discharges the capacitor in a tiny fraction of a second. Why does charging take … Exercise (PageIndex{1}) When is the potential difference across
Capacitor and Capacitance
This time span is called the charging time of the capacitor. ... Using the formula, we can calculate the capacitance as follows: (begin{array}{l}C=epsilon _{0}frac{A}{d}end{array} ) ... Energy stored in a capacitor is electrical potential energy, thus related to the charge Q and voltage V on the capacitor. ...
Charging a Capacitor
Charging a Capacitor. When a battery is connected to a series resistor and capacitor, the initial current is high as the battery transports charge from one plate of the capacitor to the other.The charging current asymptotically approaches zero as the capacitor becomes charged up to the battery voltage.

8.4: Energy Stored in a Capacitor
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). This work becomes the energy stored in the electrical field of the capacitor. In order to charge the capacitor to a charge Q, the total work ...
