Effect of dielectric on electric field? (Don't give copy-paste answer)?

Question

Answer

Dielectric are insulators...every di electric molecule can be considered a tiny dipole.....so their direction is random, therefore net dipole moment is zero but when Electric Field is applied these tiny dipoles experience torque and get themselves Aligned in the direction of Field and charges appear at the surface . this is polarisation and because of this electric field inside Dielectric gets reduced by a factor of K.

NOT COPIED THIS ANSWER FROM ANYWHERE...SO I NEED 10 UPVOTES.

Answer

Faltu question pucho to sab answer se bhar denge forum ko...lekin kuch padhai wala pucho to koi nazar hi nahi aata

Answer

Dielectric will reduce the electric field

Answer

A dielectric is an insulater that can be polarized by an appling a electric field. if it is placed in an electric field, electric charges do not flow through the material as they do in an conductor but only slightly shift from their equilibrium positions or the way in which they are moving causing dielectric pololarisation.. dielectric must be good insulator so as to minimize any DC leakage current through a capacitor.

bhai isse jada mujhe kuch bhi malom nahi quoki ye topic abhi aage syll me ayga

ques bahut acha tha magar pura nahi aya

Answer

Effect of Dielectric on Electric Field

Dielectric materials are non-conductive substances that are used to separate and insulate conductive materials in electrical systems. When a dielectric material is placed in an electric field, it can have a significant effect on the distribution and strength of the electric field. Let's explore the various ways in which dielectrics impact electric fields.

Polarization of Dielectric Material:
- When a dielectric material is subjected to an external electric field, the electric dipoles present in the material align themselves with the field.
- The alignment of these dipoles creates an induced electric field that opposes the applied field.
- This alignment process is known as polarization, and it leads to the redistribution of charges within the dielectric material.

Reduction of Electric Field:
- The presence of a dielectric material between two charged conductors reduces the electric field between them.
- The induced electric field within the dielectric cancels out a portion of the applied field, resulting in a weaker net electric field.
- This reduction in the electric field strength is proportional to the permittivity of the dielectric material.

Enhancement of Capacitance:
- Capacitance is a measure of the ability of a system to store electrical energy.
- The introduction of a dielectric material between the plates of a capacitor increases its capacitance.
- The presence of the dielectric reduces the electric field between the plates, allowing for a higher charge storage capacity.
- The capacitance of a capacitor with a dielectric material is given by the equation C = κε₀A/d, where C is the capacitance, κ is the relative permittivity of the dielectric, ε₀ is the vacuum permittivity, A is the area of the capacitor plates, and d is the distance between them.

Dielectric Breakdown:
- If the electric field becomes too strong or the voltage exceeds the dielectric's breakdown strength, the dielectric material can undergo dielectric breakdown.
- Dielectric breakdown occurs when the insulating properties of the dielectric are compromised, leading to the flow of current through the material.
- This breakdown can result in damage to the dielectric and the electrical system.

Conclusion:
In summary, the presence of a dielectric material in an electric field leads to polarization, which in turn reduces the strength of the electric field. This reduction in the electric field results in an increase in capacitance and can be beneficial in various electrical applications. However, it is important to consider the limitations of dielectric materials and ensure that the electric field does not exceed their breakdown strength to avoid damage and failure in electrical systems.
