What is the effect of inserting a dielectric other than air vacuum between the plates of a capacitor?
It usually increases the value of the capacitance.
When excessive voltage is applied to a capacitor it will break down What factor of the capacitor has the greatest effect on breakdown voltage?
The dielectric material between the plates.
Does a magnetic fIEld have an effect on a capacitor placed in between the plates?
Does a magnetic field have an effect on a capacitor when it is placed between the plates? Yes, a magnetic field between the plates of a capacitor would have some effect. Without more information it is difficult to determine how much.
What are the factor affecting capacitances of capacitance?
The area of the sheets, the distance between them, and the material between them.
What effect a capacitor has on a supply current on an inductive load?
it will improve the power factor... The angle between voltage and current will decrease depends on capacitor value.
What is a feed through capacitor?
A feed through capacitor is a type of capacitor (if you don't know how a capacitor works, look this up before going on) for bypassing RF voltage frequencies to ground of a transmitters chassis. It is built by putting a dielectric around a conductor and encasing it in a metallic tube.. so that the conductor is one plate and the outer tube is the second plate. They are shown in a schematic diagram by a straight line and a half moon to the side much like standard capacitor with the exceptions there are three connections. Two for the conductor plate and usually one for the outer shield. The higher frequencies that travel down the conductor plate 'pass through' (no current flows through the dielectric of a capacitor, unless it is leakage current or breakdown current) the dielectric to the outer case (typically grounded), while the lower frequencies (and DC) continue on through the conductor. So, in effect, what a bypass capacitor does is pass the DC current through it while bypassing the AC to ground of the chassis. The value of the capacitor will determine the capacitive reactance and what frequencies will pass more freely to ground.
What is dielectric constant?
A dielectric is an insulating material that does not conduct electricity and is transparent to an electromagnetic field. Dielectric materials are used to separate conducting surfaces such as the plates inside a capacitor, wires inside transformers, electric cable conductors, and elsewhere in the electric industry where electrical separation of charged elements is necessary. The dielectric constant is a ratio of the capacitance of a capacitor in which a particular insulating material is the dielectric, to the capacitance of the capacitor in which a vacuum is the dielectric.
How capacitor cancels inductive effect?
A capacitor try to leads the current while a inductor tries to legs the current so they cancels each other's effect ....
What is the effect of temperature on dielectric constant of a dielectric?
Usually, dielectric materials have permanent dipoles. As temperature increases, the molecules in the dielectric have more thermal energy and therefore, the amplitude of random motion is greater. This means that the molecules are less closely aligned with each other (even in the presence of an electric field). Hence, the dielectric constant reduces.
How you can reduce the effect of armature reaction?
by using capacitor
The effect of resistance on the rate of charging or discharging a capacitor?
If the resistance is in series with the capacitor, the charge/discharge time is extended.
Effect of shorting out the capacitor in a clamping circuit?
Any circuit using a capacitor will not work if the cap is short-circuited.
