Can you replace 1.7 microFarad capacitor with 2 microFarad capacitor of capacitor start motor?
It should work okay as long as voltage rating is equal to or greater than the capacitor you are replacing.
What is a disc capacitor?
A ceramic disc capacitor is a capacitor constructed with a ceramic disc as the dielectric. You'll recall that the basic definition of a capacitor is two conductors separated by an insulator (dielectric) of some kind. As a charge is driven onto one plate of a capacitor, the extra charge there builds up an electric field. Each charge arriving on one plate forces a charge off the other plate. Charge (and, therefore, voltage) builds. Let's build one to see how it works. Imagine a thick coin of some kind, but made of ceramic. You will (of course) have a ceramic disc. If you coat each face with metal and attach a lead to it, you'll have the basic construct. Note that the edges of the disc are left uncoated, and the two faces, which are conductive now, are insulated by the disc. Just dip the capacitor into a phenolic or epoxy to coat it and it's ready to go, except for the labels. These caps are used in tuning or decoupling applications in RF circuits. And the leads are a dead giveaway to their through-hole use. Crimped or straight leads, please? Use the link below to view some pictures, and all this will make a lot more sense.
Is capacitor polarity sensitive?
Some capacitors are polarity sensitive; some are not. It depends on the design. Electrolytic capacitors, for instance, are polarity sensitive, while ceramic disc capacitors are not. You can generally tell, if the capacitor is marked with polarity signs, such as + and -, if it is or not.
What is the function of a capacitor in motor circuit?
Mostly capacitor is used in the induction motors to improve the power factor , and make them to work as a self starting machine. In the small size , capacity dc motor has capacitor across it to smooth running without spark
What is dc link capacitor?
when the DC current flows through the capacitor .the leakage of the charges is in capacitor called Dc leakage capacitor .
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 is the basic difference between disc type capacitor and electrolytic capacitor?
A: it is the value disc type are small while electrolytic are big in value.The dielectric in a disc capacitor is ceramic, the dielectric in an electrolytic capacitor is a very thin corrosion layer on one of its metal foil plates.The conductive plates in a disc capacitor are two metal thinfilms on opposite sides of the ceramic, the conductive plates in an electrolytic capacitor are one of the metal foil plates and the electrolyte paste between the metal foil plates.A disc capacitor is ready to sell and use as soon as it has been built, an electrolytic capacitor will not work at all when it is first built (it is an electrical short circuit) it must be formed by passing a controlled current through it for several hours to cause corrosion of one of the metal foil plates.The parasitic inductance of a disc capacitor is less than that of any other type of capacitor, the parasitic inductance of an electrolytic capacitor is greater than that of any other type of capacitor. This makes disc capacitors better for use in circuits involving high frequencies and electrolytic capacitors better for use in circuits involving very low frequencies and/or DC.The parasitic resistance of a disc capacitor is extremely high resulting in extremely low leakage, the parasitic resistance of an electrolytic capacitor is low resulting in high leakage. In fact this leakage current in an electrolytic capacitor is essential to keeping it healthy and working in use, without it the corrosion layer dielectric slowly dissolves away into the electrolyte paste. Reversal of polarity of an electrolytic capacitor dramatically hastens this, rapidly removing the corrosion layer and shorting the capacitor resulting in both uncontrolled heating and electrolysis of the water in the electrolyte paste; the extremely rapid generation of gases causes a violent explosion of the electrolytic capacitor!The capacitance of a disc capacitor tends to be low in relation to its physical size compared to other types of capacitor, the capacitance of an electrolytic capacitor is higher in relation to its physical size than any other type of capacitor. This is due mostly to the differences in the thickness of the dielectrics.
What if your washing machine capacitor does not work?
YES THERE ARE TWO (2): 1. STARTING CAPACITOR 2. RUNNING CAPACITOR
How much uranium can the flux capacitor hold?
The flux capacitor is now only a phantasy. Flux capacitor will not work with Uranium. It has to be Plutonium.
Can capacitor work in dc?
Yes.
Can you replace 1.7 microFarad capacitor with 2 microFarad capacitor of capacitor start motor?
It should work okay as long as voltage rating is equal to or greater than the capacitor you are replacing.
Why it is necessary to connect ceramic disc capacitor across filter capacitor?
The filter capacitor has inductance and is therefore not very responsive to short term transients, i.e. fast rising or falling current edges. The ceramic disk capacitor, on the other hand, has very little inductance, and therefore is very responsive to short term transients. It is normal "best practices" to connect a small ceramic disk capacitor at each IC's Vcc terminal while also using bulk capacitance in the power supply and at various other places. For the same reason, you want a ceramic disc at the main filter capacitor in the power supply.
Can you replace a 135D capacitor with a 138D capacitor?
its only three different so.......it should work! i think...

Any circuit using a capacitor will not work if the cap is short-circuited.
