Does 001 farad of capacitor have polarity?
Only electrolytic capacitors (tantalum capacitors are a type of electrolytic capacitor) are polarized.0.001 farad = 1000 microfaradThis is a value that is too large for any practical capacitor except an electrolytic, so yes it will be polarized.
Why don't ceramic capacitors have positive and negative terminals?
Normal Case:Normally one will not find a polarity associated with a capacitor. Indeed, the quality of the manufacture would be put into question is the capacitor functions differently with different sign for the applied voltage.Abnormal Case:While common resistors are expected to function independent of polarity, it is possible to create resistors which are nonlinear and nonsymmetric in response to applied voltage. Just as diodes are nonsymmetric, one can imagine a diode-like material incorporated into the material of the capacity. There is no clear application for a nonsymmetric capacitor.The only reason to label a capacitor as preferring one side positive over the other might be the effect of the rate of discharge is one of the charged surfaces is exposed to an environment which preferentially picks up or loses charge and there by affects performance.
What is mov capacitor?
A capacitor used to protect the transformer if these any problem in the cct.
How a trimmer capacitor use?
A trimmer capacitor is a semi-adjustable capacitor placed across a variable tuning capacitor and pre-set to allow the main capacitor to track correctly with another variable capacitor on the same shaft. The adjustment takes out any differences introduced by the connected circuit.
Can a capacitor charge to its maximum by applying any voltage to it?
A capacitor can charge to its' maximum OR the voltage applied to it, whichever is LESS.
Regarding Capacitors- can any general capacitor work on a circuit diagram that shows a polarized capacitor or do you need a special capacitor for polarization?
A Polarized capacitor means that the capacitor is polarity sensitive. if you were to connect the capacitor incorrectly the capacitor would blow up. A capacitor that is marked as being polarity sensitive will have the negative lead labeled usually with a white strip. These capacitors can only be used in conjunction with a dc source. Always consult a professional when installing electrical equipment.
What causes fan to run in reverse?
(1)What happens when polarity of the fan is reversed? It depends upon your definitions of reversal of capacitor,in a series circuit reversing a capacitor in the actual sense means not a mechanical reversal by changing its metal leads,its just reversing the current direction in the capacitor. (2)Now next question is does fan capacitor have a polarity? Ofcourse it has,all capacitors have polarity,but fans capacitor is not electrolytic capacitor,so it doesnt have inbuilt polarity. (3)How we recognize the polarity of capacitor of a ceiling fan? Since it doesnt have inbulid polarity,the direction of the current entering the mesh determines positive polarity and current leaving is assumed as negative polarity.while doing mathematical analysis we can take any convention it will not affects the magnitude since we are taking modulus in calculations. (4)Final Assumption reveling the facts about fans reverse rotation If we connect the fan in such a way that currrent is leaving or reversing the direction of current,the capacitor polarity changes and fan will rotate in reverse(since it is a single phase induction motor{note: rotating magnetic field and working of fan}),need of the capacitor is it gives the initial torque and technically improves the power factor,capacitor charges and discharges with respect to the frequency of the ac and gives the stability to the system,its efficiency will be lower and speed reduces if we remove the capacitor theoratically,so finally you can say the fan rotates reverse if we change the polarity of the capacitor(indirect meaning of changing direction of current).if you want any simple mathematical analysis of the detailed explanation,mail me at "ellipsis047@gmail.com" or call me 07259434969 "Sreenath SM(India)".i can make you understand the basis of all analog and electrical circuits.

Why the resistor does not have polarity?
they do not have any electrical property that is polarity sensitive

What does a disc capacitor do?
A disc capacitor does exactly the same thing that any other capacitor does, with one difference: it has the lowest value of parasitic inductance of any type of capacitor. As inductance is exactly the opposite property to capacitance, its presence in a capacitor is very undesirable in many applications and can sometimes result in circuit instability.

What does polyester capacitor do in a circuit?
same as any other capacitor. however they are usually used where higher voltages are.
How can you use a 3 phase capacitor as a single phase capacitor?
Just use any two of the three terminals that are available, this will give you a single phase capacitor.
Why the capacitor motor will not develop any starting torque without capacitor?
The start winding needs a capacitor in series with it in order to produce a phase shifted magnetic field that will develop the torque necessary to bring the rotor up to operating speed. Once operating speed it obtained, a centrifugal switch opens and disconnects the start winding - the rotor's inertia can then keep it going as needed.
Effect of shorting out the capacitor in a clamping circuit?
Any circuit using a capacitor will not work if the cap is short-circuited.
