Efficiently Building a Small Capacitor Bank for a 9V Battery

AI Thread Summary
Building a small capacitor bank for a 9V battery can be efficient, but the design depends on the specific energy requirements and discharge time. The goal is to absorb power quickly and release it in a short duration, ideally within a few minutes. Participants suggest that while a capacitor bank can store energy over time, it may not be the best option for rapid discharge needs. Super capacitors are mentioned as a potentially more suitable alternative for quick energy absorption and release. Providing more details about the energy involved would help in determining the best approach for the project.

I've been interested in building a capacitor bank (a very small one for a simple 9V battery) but I'm not really sure how I should go about doing this. I've researched into other ways and found this would be the most efficient.

I was going to try this the bank absorb as much power as it can in as little time as possible, any recommendations on how I could go about doing this?

Generally the advantage of a capacitor bank is that you can absorb lots of power over a long long time and then release it in a very very short time. Not sure what you are thinking of in terms of 'as little time as possible'.
 
Hmm, well I'm looking to have it absorb and discharge within a few minutes. So I'm assuming the cap bank isn't the best idea?
 
You will need to supply more information on how much energy is involved.
 
I sent you my calculations, it's frustrating trying to solve a problem when you know there is so many better options out there. Thank you for your help, Nova & Berk. I really do appreciate it.

Also, do you think a Super capacitor would be more suitable for my experiment?

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'How Does Jaguar's 1980s V12 Dual Coil Ignition System Enhance Spark Strength?'

Thread 'How Does Jaguar's 1980s V12 Dual Coil Ignition System Enhance Spark Strength?'

I have come across a dual coil ignition system as used by Jaguar on their V12 in the 1980's. It uses two ignition coils with their primary windings wired in parallel. The primary coil has its secondary winding wired to the distributor and then to the spark plugs as is standard practice. However, the auxiliary coil has it secondary winding output sealed off. The purpose of the system was to provide a stronger spark to the plugs, always a difficult task with the very short dwell time of a...
