How do you wire a capacitor to a 12 volt car battery to have as much voltage as possible?

I assume you are wiring up one of those obnoxious window-rattling bass thumpers that require a massive capacitor for quick response. Well you can't increase voltage any way you install it and if you did the whole system would fry and set your car on fire. What a capacitor does is store a lot of power that can be released as a massive current surge when the amp wants it. Wire it AS INSTRUCTED by the manufacturer and don't modify the wiring! If you want more power buy a bigger amp. There are no shortcuts.

What happens when a capacitor connected across a battery for a long time?
For a long time, The capacitor will be charged to the voltage of the DC battery, the positive side of the capacitor touching the positive terminal of the battery. Not much DC current will conduct, except for some tiny leakage current due to imperfection of the cap. The battery will be drained eventually.
Does a 7200mAh battery last longer than 4400mAh?
mAh stands for milliamp hours and is a partial measure of the energy that can be stored in a battery. It is the standard used for rechargeable batteries but rarely used for non-rechargeable batteries. The rating is only a partial measure because the voltage affects the total energy stored. For a given mAh rating, the higher the voltage of the battery, the more energy can be stored. For two batteries that deliver the same voltage, a 7200mAh battery will store more energy than a 4400mAh one. Therefore, the 7200mAh battery should last longer. There are other factors that affect how long a battery can last. The type of load can have a significant effect on the battery life and the condition of the battery itself.
Have lights and radio but want start on a 1997 Chevy silverodo 1500 series?
you may only have enough voltage to run some accessories. i believe a starter needs at least 9 volts to turn an engine over. how much voltage does yours have?? check the voltage as you start it too with a meter. sometimes and rare it is it may have a fault inside the battery that opens when you put too much of a load on it.
In a parallel circuit does the battery run out very quickly?
No, it will run out just as much as if you put it in a series circuit. Parallel circuits involve the same voltage or amperage to go to each component.
What is 6 AAA batteries?
. There is an AA battery (technically it is a cell, not a battery) that is part of the series D, C, AA, AAA, AAAA. There are holders which hold 6 AA cells in series, creating a nominal voltage of 6 x 1.5 equals 9 volts, but with much more capacity and current capability then a nine volt battery.
Describe the response of a capacitor when connected to and then disconnected from a battery?
A capacitor that is suddenly connected to a battery will charge to the battery voltage. The time to do this is dependent on the current capacity of the battery and wiring, and the capacitance of the capacitor. This represents an instantaneous short circuit, which lasts for a (usually) very short time - but damage could be done if there was no resistance. A charged capacitor that is suddenly disconnected from a battery will hold that voltage. The length of time it will hold is dependent on how much leakage current there is.
Why is voltage rating of a capacitor important to the user?
The voltage rating of a capacitor tells the user how much voltage the capacitor can withstand. If a user exceeds this voltage, the capacitor's dielectric may be damaged and destroyed.

What happens to the charge if you double the voltage across a capacitor?
In order to double the voltage across a capacitor, you need to stuff twice as much charge into it.
Is it possible to find out how much voltage is stored in a solar cell?
A solar cell does not store electricity. It charges a battery that stores electricity. The voltage of a battery can be found by connecting a voltmeter to the battery terminals.
When should you put a capacitor in your car?
When a stereo system drains too much battery power, it is time to add a capacitor. The capacitor will not increase the battery, but instead will modulate it allowing for additional stereo usage.
Why is there a voltage drop across the terminals of a chemical battery that is worn out?
Hi, The voltage may not drop all that much since a battery's output is a specific current at that rated voltage. It possible to place a digital multimeter on a 1.5 volt battery and see 1.5 volts. However, the battery could be as dead as a doornail. Hope this helps, Cubby
How many current drawn in 400 kvar capacitor bank?
It depends upon at how much voltage level 400 kvar capacitor bank is used.
What does the voltage rating of a capacitor mean?
The voltage rating of a capacitor is the maximum amount of voltage that a capacitor can hold. Going above this rating can damage and destroy the capacitor.AnswerExceeding a capacitor's voltage rating can cause its dielectric to break down. A capacitor's voltage rating is generally expressed as a d.c. voltage so, if it is to be used with an a.c. system, it's necessary to know the peak value of the a.c. voltage, which is determined by dividing the a.c. (rms) voltage by 0.707.
