What is pressure coil capacitance?
The series resistance (swamping resistance and multiplier) in pressure coil circuit has many turns.So in addition to inductance seen before, there are inter-turn capacitance also.If this capacitance effect exceeds the inductance effect, a phase-shift in pressure coil current will cause an error.When pressure coil capacitance roughly equals the inductance, the errors cancel each other.In most cases the inductance is more than the capacitance and thus the shunting capacitor mentioned before will serve the purpose.
How do you short the capacitor?
There is no resistance between cathode and anode when measured with a multimeter. You can also lick the terminals. If charged, it'll taste much like the terminals of a 9v battery, which, interestingly, tastes much like going down on a girl.
How do you calculate kvar of capacitor bank if you know only the kw?
Your question is rather vague. Are you asking how do you determine the reactive power of a capacitor bank necessary to improve the power factor of a load (in which case, is it a single-phase or a three-phase load), or are you asking how to convert a capacitor bank's capacitance into reactive power?If the former, then you need to know the reactive power of the load before power factor-improvement, and the resulting reactive power after power-factor improvement, and the difference between these two will tell you how much reactive power you need to add in the form of capacitors.
Why you use capacitors before and after regulator ICs in a voltage supply circuit?
The capacitor before the IC is filtering the output of the rectifier, so that the minimum voltage dip between diode conduction cycles is greater than the minimum voltage the IC requires. The capacitor after the IC is stabilizing the IC, by preventing it from oscillating, and responding to quick changes in load faster than the IC can.
What causes a capacitor to blow?
Capacitors can fail for a few reasons, and sometimes the do "blow". Capacitors have voltage limitations which, if they are exceeded may cause internal arcing or flashover. Once initiated, arcing can cause sudden heating and if the circuit supports high enough energy the capacitor can be damaged and may actually come apart. For polarized capacitors, reversing the polarity may even result in catastrophic failure at normal voltage levels. Another reason capacitors fail is as a result of high current. If a capacitor is subjected to high frequency currents of sufficient magnitude internal heating can result and once again damage will result. With enough energy it may come apart. One last way capacitors may be damaged is through sudden discharge. Generally high voltage ceramic capacitors may be charged to high energy levels. With a sudden discharge ceramic capacitors can respond with a piezoelectric effect and the ceramic may actually shatter.
I charged a homemade capacitor with a 9v you touched your tongue to the capacitor and you got no charge?
In order to feel 9V on your tongue, you need enough current, for enough time, for your brain to recognize the current.Homemade capacitors tend to be rather low in capacitance. The resistance of your tongue might then discharge the capacitor rather quickly, and you might not notice the voltage before it goes to zero. Try this with a large capacitor, such as a few hundred microfarads and see what happens. Please do not charge the capacitor to more than 9V - you do not want to hurt yourself!
How long will it take to fully charge a capacitor in a series RC ciRCuit with a 6microfarad capacitor 2Kilohm resistor and 141 volt supply?
The time it takes to fully charge a capacitor depends on the capacitance and resistance of the circuit; the voltage is irrelevant. The equation you need is:t = 5RCwhere: t = time in seconds, R= resistance in ohms, and C =capacitance in farads.So you should now be able to calculate the time for yourself, but remember to convert the resistance into ohms and the capacitance into farads before you insert the figures into the equation.
How do you discharge high dc voltage capacitor?
When a capacitor is powered off in an energized circuit, the capacitor still stores a certain amount of electricity. When there are other loads or components in the circuit, they will slowly discharge, or they can be quickly discharged by short-circuiting with small resistors or wires (at low voltage). When the capacitor discharges, the two poles of the capacitor respectively carry a certain amount of charge, and the outside world and the capacitor form a closed loop (generally, the closed loop does not include a power supply). The excess electrons (negative charges) approach the positive electrode of the capacitor to form a current, so that the charges at both ends of the capacitor are neutralized. When the neutralization is completed, the electric field between the two electrodes of the capacitor disappears. However, this is in an ideal situation. The amount of terminal charge is exponentially neutralized towards zero, but not zero. Discharge requirements of capacitors After the capacitor is disconnected from the bus, it must be discharged through a discharge resistor or a special voltage transformer. Discharge should be performed between the lead wires of the capacitor and between the lead wires and the casing. The capacitor can be grounded after the capacitor is discharged. Before working on the capacitor, be sure to conduct a test discharge. This discharge is to place the discharge rod on the terminal of the lead wire of the capacitor for a period of time. Even if both sides of the capacitor device are grounded, in order to prevent residual charge on the capacitor, a test discharge must be performed, and each group of capacitors connected in parallel must be discharged. Special care should be taken when conducting inspection discharge of capacitors removed due to faults. Due to the damaged capacitor, the general grounding device may not function as a ground discharge due to a partial disconnection. If the capacitor device has an interlock device, it should be considered that only after the entire device is grounded, the small door of the capacitor bank protective fence can be opened.

Why do you have to charge your capacitor?
well...a capacitor RELEASES charge which if BUILT up. that's why... lets say that you have a bucket...and you want to flood a small area...you need to fill up ( charge) the bucket before you can flood (discharge) ANSWER: It has the possibility to discharge if a path can be found. ITS property is to store potential

Can you replace a 2200 uf cap with a 1000 uf?
Replacing a 2200 µF capacitor with a 1000 µF capacitor is generally not advisable, as the lower capacitance will result in reduced filtering and energy storage capacity. This may lead to instability or insufficient power supply performance in circuits that require the specific capacitance for proper operation. Always check the circuit requirements before making such substitutions.
How does the capacitance change if the voltage across the capacitor is doubled?
As capacitance is not affected by voltage, nothing will happen! Capacitance is affected only by the area of overlap of the plates, their distance apart, and the permittivity of the dielectric.
What is a capacitance?
capacitanceis the ability of a body to store charge in anelectric field. Capacitance is also a measure of the amount of electric potential energy stored (or separated) for a given electric potential.AnswerA capacitor is a device that will store electrical energy. This energy is stored in its electric field. This is achieved by separating the charge on its plates -contrary to popular belief, it does not store that charge, as the net charge remains the same after charging as it was before charging.
How can I troubleshoot and fix a blown capacitor in an AC unit?
To troubleshoot and fix a blown capacitor in an AC unit, first turn off the power to the unit. Then, visually inspect the capacitor for any signs of damage such as bulging or leaking. If the capacitor is blown, you will need to replace it with a new one of the same specifications. Make sure to discharge any stored energy in the capacitor before handling it. Install the new capacitor following the manufacturer's instructions, and then turn the power back on to test the unit. If you are unsure or uncomfortable with this process, it is recommended to seek help from a professional HVAC technician.
Why current leading in capactor?
In the ac waveform of a capacitor the current waveform leads the voltage waveformcurrent is large to start until capacitor fills with it's voltage charge if that helpsAnswerThe terms 'leading' and 'lagging', used when describing power factor, are defined in terms of whether the load current is leading or lagging the supply voltage.In a capacitive circuit, the load current leads the supply voltage, so the power factor is leading.
How long should you wait before capacitors have completely discharged?
Generally, it is recommended to wait for 5 times the time constant of the circuit for capacitors to completely discharge. This means waiting for about 5RC, where R is the resistance in the circuit and C is the capacitance. However, for safety reasons, waiting for a few minutes to ensure complete discharge is a good practice.
Do you get discharge if you have not had your period?
Yes. You get discharge before you get your period.
