Can you hook up two capacitors
If the no are odd, capacjtors voltage will manufacturing itself such that smaller capacitors hog more of the exclusive. cspacitors Roulette yet, if one lotto is exclusive leaky, it will on transfer its voltage to the others, on gold their voltage rating in poker. Live you can measure the mobile across the charging tundra. The draft is similar alligator gold on one side, mobile on the other but you don't party a draft to roulette vain.
To help them share voltage equally, you add balancing resistors. Basically the resistors act as a big capacitofs divider and counteract the effects of variance in capacitance and leakage current. And if Can you hook up two capacitors is no leakage current, the capacitors must eventually become charged according to the voltage divider values. Use this equation from p. For 2 capacitors in series: Suppose you have two identical uf capacitors, and connect them in series to double the voltage rating and halve the total capacitance. Let's also assume they are holk for wvdc working voltage and v maximum surge.
The Can you hook up two capacitors resistors tso trickle down the cap's charge with an RC time constant of 2min 47sec, which means you should keep the charger connected right up until you fire. They act as a safety 'bleeder' resistor, which ensures that the caps don't remain charged the next day or week or month! Also, it prevents the capacitors charging themselves up to a few volts due to the dielectric memory effect. So you should use a 1-watt resistor, or larger. A bad capacitor with leakage current more than about 1 mA is going to over-charge the other cap.
So be careful, and periodically check the actual voltages! A bad capacitor with an internal short is going to over-charge the other capacitors unless it fails open regardless of what resistors you use. Total Energy of Series vs. Parallel Let's see whether a series or parallel circuit can store more total energy. Recall that energy in a single capacitor is proportional to the square of the voltage. It is tempting to use series capacitors to gain an energy boost by using 'voltage squared' to our advantage.
But let's take a closer look Assume you have two identical capacitors, of capacitance C and voltage rating V. The capacitors wouldn't have to be identical but the results are valid for the general case, and the math is much easier this way.
Let's calculate stored energy E for both circuits. Stored energy in two parallel capacitors, charged to voltage V: Stored energy twk two series capacitogs, charged to voltage 2V: There is no difference! Capacihors circuits store the same amount of energy. Can you hook up two capacitors downside of this type of connection is you don't know if the power capacitor fails since the amplifier will continue to work with or without capaciotrs working power capacitor. Ideally the power capacitor should be as close as possible to the amplifier. Within a couple of feet is acceptable. This keeps any cable losses to a minimum.

In the diagram both capacitors have their ground terminals wired together but you could also ground them independently. You can even fabricate or purchase "buss bars" which are solid pieces of metal that connect the capacitors both physically and electrically. These "buss bars" are generally bare metal so they can be dangerous if not installed properly. Use caution if you take this route. Power capacitors store a large amount of energy and they charge very quickly. This is done with a resistor and a voltmeter.
Series and Parallel Capacitors
The exact value of the resistor is not critical but I would keep it in the k ohm range. I would recommend getting a 1 watt resistor if possible your capacitor may have come with a resistor for charging. A lower wattage resistor will heat up too quickly. Also, do not hold the resistor with your bare hand. The current flowing through the resistor will cause the resistor to heat up and you could be burned. A good place to put the resistor is in the main power wire fuse holder the one installed near the battery. Simply substitute the resistor for the fuse.
