Are capacitors a viable option for storing charge in electronic circuits?

In summary, capacitors are useful for storing charge because they can smooth out fluctuations in voltage and provide a steady flow of energy. However, they are not efficient for long term energy storage and are better suited for short bursts of energy. Rechargeable batteries and capacitors both store energy, not just charge. When it comes to backup energy storage, factors such as size, voltage, cost, and energy capacity need to be considered. It is not possible to store energy in a generator, as it converts mechanical energy into electrical energy.

Capacitors are great for quick discharges of energy that batteries could only dream of doing. The classical example is the flash of a camera. It would take a battery a long time to discharge the needed energy for the flash, and it would be beyond infuriating to have to wait standing still God knows how long until the camera finally releases the charge.

You will also learn in your electronics course that the Capacitors are also very useful in AC to DC converters because they help reduce the Ripple voltage.

As for the textbook, I highly recommend this one:

I used a different one for my electronics course, and honestly speaking I didn't like it too much. It felt too theoretical without enough real life examples to understand what was going on. I will use the one in the link a gave above for my digital electronics class next semester and from what I've seen so far it is much better and easier to read than the one I used.

I suggest reading part one: Solid State Electronic and Devices. Parts two and three are for more advanced courses.

And just in case, this is the book I used for my course:

If you are going to buy one, then I suggest the first one. If you will get them digitally, try to get both and use them as references.

Cheers.

I don't think it's rudeness - it is just lack of empathy. Some people just latch on a particular interpretation of an idea and don't see the way the rest of the World (the 'informed' world) view it. They decide that they are 'right' and cannot reconsider. Can be quite a nightmare in personal dealings in the real world. Happily, on a forum like this it doesn't represent a problem.

Thread closed for now. I'll try to have a look at it after the holiday.

EDIT -- Thread will just remain locked. Let's try not to be so argumentative over terminology, especially trying to push non-standard terminology.

Ratch -- check your PMs.
