Capacitors (7 of 9) Energy Stored in a Capacitor, An Explanation

Күн бұрын

Explains how energy is stored in a capacitor and how to calculate the work done by the battery and the amount of energy stored in the capacitor.
A capacitor is a passive electronic device that stores electric charge on its plates and electrical energy in its electric field. A capacitor contains at least two electrical conductors such as metal plates that are separated by a dielectric. The insulating dielectric acts to keep the metal plates isolated from each other and to increase the capacitor's ability to store charge. Materials commonly used as dielectrics include glass, ceramic, plastic film, paper, mica and air. Unlike a resistor, an ideal capacitor does not dissipate energy. The SI unit of capacitance is the farad (F), which is defined as one coulomb per volt (1 C/V).

Thanks for this explanation ! I assume if we plot a Voltage vs Electrons transferred graph, we can see the first point (first electron) has 0V, and the last point (last electron) has 9V, it will look like a linear ascending line from 0 to 9V. This forms a triangle which is half of total charge (Q) * voltage (9V)

Yes, and this example suffers by showing a 9V battery, which implies that as soon as the switch closes the capacitor plates are at 9V. It would be better to replace the battery with a current source, and show it charging the cap from zero volts to 9V.

would like to ask so how is the total energy taken from the battery during the charging process is different to the total energy of the battery?

Where does half the energy go? If you were to go by the definition of potential difference (work done to move 1 C charge across) then we find that V=W/Q and we know that W = Q V/2. But if we were to sub in a value for V ie. W = Q W/ Q 2 (Q gets cancelled) W = W/2 or 1= 1/2 and that's not true so how is the energy magically halved? Where does half the energy go? Heat is obviously not the answer but where else could this 1/2 go?
