What is the dielectric constant of rubber

What may be defined as an effect in a dielectric material similar to the hysteresis found in a magnetic material?

The overall effect of connecting capacitors in what way is to move the plates of the capacitors further apart?

Ceramic capacitors usually range in value from 1 picofarad to 0.01 microfarad and may be used with voltages as high as how many volts?

An electrolytic capacitor has two primary disadvantages compared to a paper capacitor in that the electrolytic type is polarized and has what other disadvantage?

A voltage divider containing resistance and capacitance is connected in a circuit by means of a switch. What is such a series arrangement called?

What is an excellent dielectric that can withstand a higher voltage a paper dielectric of the same thickness?

What is the time required to charge a capacitor to 63 percent (actually 63.2 percent) of full charge or to discharge it to 37 percent (actually 36.8 percent) of its initial voltage known as what property of the circuit?

Dry electrolytic capacitors vary in size from about 4 microfarads to several thousand microfarads and have a working voltage of approximately how many volts?

A dielectric material, or insulator, is rated as to its ability to respond to electrostatic lines of force in terms of a figure called what?

Which units are used to measure capacitance?

What is the dielectric constant of a vacuum?

Which capacitor property is the maximum voltage that can be steadily applied without danger of breaking down the dielectric?

The power loss of a capacitor is determined by loss in the what?

Which type of material must be between the plates of a capacitor?

How many months can a high quality capacitor hold its charge?

What is the current called which appears to flow through a capacitor?

Which law states that the voltage across a resistance is equal to the current through the resistance times the value of the resistance?

What way are capacitors connected when one plate of each capacitor is connected directly to one terminal of the source, while the other plate of each capacitor is connected to the other terminal of the source?

Paper capacitors usually range in value from about 300 picofarads to about how many microfarads?

The working voltage of a paper capacitor rarely exceeds how many volts?

Common values of mica capacitors range from approximately 50 picofarads to what?

Many capacitors will use oil with another dielectric material to prevent arcing between the plates. If arcing should occur between the plates of an oil-filled capacitor, the oil will tend to reseal the hole caused by the arcing. What is such a capacitor referred to as?
