What is the unit of dielectric strength?
In SI, the unit of dielectric strength is volts per meter (V/m). In U.S. customary units, dielectric strength is often specified in volts per mil.In physics, dielectric strength 2 meanings:Of an insulating material, the maximum electric field that a pure material can withstand under ideal conditions without breaking down.For a specific configuration of dielectric material and electrodes, the minimum applied electric field that results in breakdown.
What happens to the strength of the electric field each particle exerts on the other?
The strength of the electric field approaches zero
Circle the letters of the factors that the strength of an electric field depends on.?
The strength of an electric field depends on the charge that causes it, and on the distance from the charge.
What happens to the electric field when you get farther from an electric charge?
An electric field gets stronger the closer you get to a charge exerting that field. Distance and field strength are inversely proportional. When distance is increased, field strength decreases. The opposite is true as well. Additionally, field strength varies as the inverse square of the distance between the charge and the observer. Double the distance and you will find that there is 1/22 or 1/4th the electric field strength as there was at the start of your experiment.
The strength of an electric field depends on the?
Electric field strength depends on direction and magnitude because it is a vector quantity.
The strength of electrodes is expressed in terms of?
CHF
What is meant by capacitor?
A capacitor is an electrical or elctronic semi conductive material which have the ability to store electrical charge and discharge when needed, and also used for timing a circuit and finally used for filtering in a circuit. A capacitor is made up of two plates seperated by die-electric strength or material. Thanks

How does a capacitor store energy?
The energy stored in a capacitor is almost entirely in the electric field produced between the plates. It takes energy from a battery or some other power source to move electrons to one of the plates and away from the other. This makes one plate positively charged and the other negatively charged. Electric field is produced in proportion to the charge per unit area on a plate, and this electric field is said to originate on positive charges and terminate on negative charges. Energy stored in electric fields is proportional to the square of the electric field strength and the volume of the field. The energy is transferred from the power source to the electric field through the rearrangement of electrical charges.

Is electric field strength scalar or vector?
The strength of the electric field is a scalar quantity. But it's the magnitude of thecomplete electric field vector.At any point in space, the electric field vector is the strength of the force, and thedirection in which it points, that would be felt by a tiny positive charge located there.

When the distance from a charged particle decreases the strength of the electric field does what?
As the distance from a charged particle increases the strength of its electric field DECREASES.
What happens when dielectric breakdown occurs?
The dielectric,usually the insulator between the plates of a capacitor, can be overstressed by the application of too high voltages applied to the capacitor plates. The dielectric breaks down and a current flows between the plates until,either they are discharged, or an equilibrium is reached,below the working voltage of the capacitor. If the dielectric is damaged in this process he capacitor must be replaced. Some dielectric material self heal and can recover from an over voltage.
What is the material use in the capacitor?
Capacitors are named after their dielectrics. So, an 'air capacitor' uses air as its dielectric, a 'mica capacitor' uses mica as its dielectric, and so on. There are lots of different dielectric used to separate the plates of a capacitor, each with different permittivities and dielectric strengths. As the perfect dielectric (i.e. one with both a very high permittivity and a very high dielectric strength) doesn't occur, the choice of dielectric is always a compromise between it permittivity and dielectric strength.
What is electric potential dependent upon?
The magnitude of the electric potential is dependent upon the particle's charge and the electric field strength.
