What the function of polarized electrolytic capacitor?
Electrolytic capacitors are used for power filter, decoupling, signal coupling and time constant setting, DC blocking, etc. Polarized electrolytic capacitors usually play a role in power supply circuits or intermediate frequency and low frequency circuits for power supply filtering, decoupling, signal coupling, time constant setting, and DC blocking. Generally electrolytic capacitors cannot be used in AC power circuits. When used as filter capacitors in DC power circuits, its anode (positive) should be connected to the positive terminal of the power supply voltage, and the cathode (negative) should be connected to the negative terminal of the power supply voltage. Otherwise it will damage the capacitor. We're JYH HSU(JEC) Electronics Ltd (or Dongguan Zhixu Electronic Co., Ltd.), an electronic components manufacturer.

How do capacitors classified?
capacitors are classified on the basis of dielectric material used inside it. For example the electrolytic capacitor consist electrolyte as dielectric mica capacitor consist mica as dielectric between plates and ceramic capacitor consist ceramic as dielectric.
What types of capacitor used in electric ceiling fans?
Electrolytic capacitors or film capacitors. The capacitor in an electric fan is used to start the motor, and the speed is controlled by the current of the governor. The size of the startup capacitor can only change the startup speed of the fan. Once the fan is started, that is, once the capacitor is discharged, the capacitor only plays the role of isolating DC. It will no longer participate in the operation of the fan. Because the capacitor only has the function of charging and discharging. ----We're JYH HSU(JEC) Electronics Ltd (or Dongguan Zhixu Electronic Co., Ltd.), an electronic components manufacturer.

Can you change 680 microfarad capacitor with 1000 microfarad at 35 volts?
Yes you can - in principle, and in many cases. As long as the form factor of the new capacitor is the same as the form factor of the former capacitor, and as long as the maximum voltage of the new capacitor is higher than the max voltage of the former capacitor, you can often replace a lower-rated with a higher rated capacitor. However... Apart from the nominal capacity and maximum voltage rating, you should also consider the capacitor's design. There are many ways to make a capacitor, from tiny ceramics over various plastics and metal foil combinations to electrolytic capacitors. Apart from the capacity and voltage rating, the different types of capacitors also vary in a lot of other aspects: impedance, precision, drift with time and drift with temperature, are just some. Electronics designers typically choose the capacitors carefully, and considering all those aspects. Only when those aspects don't matter much, designers tend to chose the cheapest technology. In such a case, you're safe to replace. In most cases of capacitors rated at 1 micro Farad and above, electrolytic capacitors are used (typically small cylinders). Those are typically selected because they offer excellent value (capacitance) for money, and you're typically safe to replace them, subject to above rules. CAUTION: some capacitors have a distinct polarity. You must make sure to observe the polatiry when replacing polarized capazitors. Failure to do so can result in serious harm (basically, the part might explode).
Which filter is used for passing only high frequency?

How ceramic capacitors can do filtering in replacement of electrolytic capacitors?
Electrolytic capacitors do a very good job of bulk filtering, but they have poor high frequency performance due to distributed inductance. The ceramic capacitor has excellent high frequence response, and will often be used in parallel to the electrolytic to filter out fast rise time step changes in current demand.
Can you explain why oil filled capacitors must be used for capacitor run motors instead of the more economical ac electrolytic types?
Electrolytic capacitors cannot be used on an AC (alternating current) system.
Why should electrolytic capacitors not to be used in AC circuits?
Electrolytic caps are polorized and are used for filtering and will charge up to a DC value as in power supplies.

Do electrolytic capacitors generally have polarity?
Yes. Electrolytic capacitors are polarized. Capacitors with positive and negative poles generally have positive and negative marks. Generally, for capacitors with pins, the long end of the pin is the positive electrode. For cylindrical electrolytic capacitors, there will be a vertical line printed on the negative side of the capacitor. SMD capacitors generally have no positive and negative poles. --- We're JYH HSU(JEC) Electronics Ltd (or Dongguan Zhixu Electronic Co., Ltd.), an electronic components manufacturer.

Does a charged capacitor block DC or AC or both?
It blocks DC or it wouldn't be charged. It passes AC through it to ground or it wouldn't filter. But in the early days charged electrolytic capacitors were used as rectifiers or AM detectors.
Why using electrolytic capacitor for dc voltage?
Electrolytic Capacitors can only be used with DC supplies because they cannot cope with AC; they are polarised and AC will cause them to blow, whether that's internal or external; in which case you've some cleaning-up to do!
Why do you use a dc capacitor in table fans while an ac capacitor in a ceiling fan?
there is no separate capacitors for AC and DC. All capacitors are same. Electrolytic capacitors are manufactured by creating a die-electric by chemical etching or electroplating on one plate. Such capacitors when connected in AC circuit dislodges the die-electric material and thus results in short circuit between the two parallel plates of the capacitor. For AC circuits only non-electrolytic capacitors should be used. The common type is oil impregnated paper capacitor.
Difference between electrolytic and non-electrolytic capacitors?
Electrolytic Capacitors:1. It provides high capacitance in small volume.2. It has got polarity.3. It is not suitable for high frequencies due to losses in dielectrics.4. It is generally available in 1-100 µF rangeNon-Electrolytic Capacitors:1. Its capacitance depends on dielctric constant of the bulk.2. It doesn't have polarity.3. It is widely used at all frequencies.4. It ranges from pico Farads to fractions of µF.
What type of capacitor should be charged slowly after not being used for a period to prevent damage if a sudden surge?
if exact replacement capacitors are not available,you should substitute it with a capacitor that has
What is the function of electrolytic cell?
The function of an electrolytic cell is to use electrical energy to cause a non-spontaneous chemical reaction to occur. This process involves passing an electric current through an electrolyte solution to produce a chemical change, such as the decomposition of water into hydrogen and oxygen gases.
