A 1-farad capacitor can store one coulomb (coo-lomb) of charge at 1 volt. A coulomb is 6.25e18 (6.25 * 10^18, or 6.25 billion billion) electrons. One amp represents a rate of electron flow of 1 coulomb of electrons per second, so a 1-farad capacitor can hold 1 amp-second of electrons at 1 volt. A 1-farad capacitor would typically be pretty big.
There are two capacitor symbols generally used in electronics. One symbol is for polarized capacitors, and the other symbol is for non-polarized capacitors.

FAQ: Exploring the Role of Capacitors in Parallel to Motors for RC Toy Cars 1. What is a capacitor with a motor? A capacitor with a motor is a combination of a capacitor and a motor in a single unit.

What is the importance of Bypass capacitor of Common-emitter amplifier? I would just like to add a bit to Phil''s answer. To be precise, for a common emitter amplifier, the emitter is tied to the signal common node thus the title "Common Emitter".. This means that, for the signals of interest, the emitter is effectively at zero volts. If the emitter resistor is not …
This is done because "real" capacitors have a series inductance - and in the parallel case, the small capacitor (which has a smaller inductance) will be able to respond quickly to rapid changes in current, while the larger capacitance will take care of "longer term" current demands. This is sometimes called "supply decoupling".

If we use two capacitors, we can power the lamp for longer. Let''s say capacitor one is ten microfarads and capacitor two is 220 microfarads. How do we calculate the total capacitance? Well, that''s very simple. The answer is 230 microfarads. The capacitors combine in parallel, so 10 + 220 equals 230 microfarads.
