animation of capacitor charging

Capacitor analogy - An analogy to the capacitor in mechanical rectilineal terms is a compression spring where the compliance of the spring is analogous to the capacitance. Representations In this analogy: Charge is represented by linear displacement, current is represented by linear..

Capacitor - Charge separation in a parallel-plate capacitor causes an internal electric field. A dielectric (orange) reduces the field and increases the capacitance...

Switched capacitor - A switched capacitor is an electronic circuit element used for discrete time signal processing. It works by moving charges into and out of capacitors when switches are opened and closed. Usually, non-overlapping signals are used to control the switches, so that not all switches are closed..

Applications of capacitors - Capacitors have many uses in electronic and electrical systems. They are so ubiquitous that it is a rare electrical product that does not include at least one for some purpose. A capacitor can store electric energy when disconnected from its charging circuit, so it can be used like a temporary battery...

  Lec 24 | MIT 8.02 Electricity and Magnetism, Spring 2002   this capacitor. And your intuition will help you a great deal without any fancy differential equations. It is clear that at T equals 0, the capacitor is not charged. There is no charge on the capacitor. And it will take time to charge the capacitor. So at T=0, you expect that the potential over the capacitor is 0. If you make T a little larger than 0, you are going to charge up this capacitor, and so the potential over the capacitor will go up, and therefore the current will go down. And ...

Question : A parallel-plate capacitor consists of two parallel circular plates separated by distance d, d is much smaller than diameter of plates. Each plate has net charge zero. What is potential energy of a point charge Q located inside the capacitor at its center, d/2 from each plate, with respect to infinity?

Answer : If the net charge on each plate is zero, then there is no force exerted on an electron brought in from infinitely far away to the point on the capacitor plate, therefore the potential energy of such an electron would be zero.

Question : I am planning to make a coil gun and i am wondering if i need to incorporate a capacitor bank charger or if i can just hook up a battery to the capacitors and have it charge. And why would it be required/optional?

Answer : Required

Question : Two capacitors are connected in in parallel an the resulting combination is connected to a 9 volt battery. ....I cannot find the formula anywhere online or in my textbook.... I just need a nudge in the right direction Thanks

Answer : The reason why is that there is no formula, its too simple. The capacitors are both charged to the voltage of the battery. They are both 9V.
