Which capacitor-store higher amount of energy?

 [A]. Air capacitor [B]. Paper capacitor [C]. Mica capacitor [D]. Plastic film capacitor

Explanation:

Energy stored is proportional to capacitance and capacitance is proportional to permittivity.

 Jitendra said: (May 29, 2014) E is directly proportional to c and c is is proportion to permittivity. And mica having higher permittivity than other.

 Deepika said: (Aug 18, 2014) What is permittivity ?

 Kal said: (Aug 20, 2014) What is permittivity?

 Chetan said: (Sep 19, 2014) It is directly related to electric susceptibility, which is a measure of how easily a dielectric polarizes in response to an electric field. It's shows ability of the material to passes the number of electric lines(imaginary lines) through the material.

 Rajeev Kumar said: (Sep 22, 2014) @Deepika. It is directly related to electric susceptibility, which is a measure of how easily a dielectric polarizes in response to an electric field.

 Rahul Kumar said: (Jan 13, 2015) @Deepika. The ability of a substance to store electrical energy in an electric field.

 Vilas Karadbhajane said: (Mar 13, 2015) How to find permittivity?

 Tejas said: (Jul 17, 2015) What is the value of relative permeability of plastic?

 Sanseep said: (Sep 20, 2015) What is susceptibility?

 Naqeeb Ullah said: (Dec 20, 2015) The susceptibility indicates whether a material is attracted into or repelled out of a magnetic field.

 Richa said: (Dec 28, 2015) What is mica?

 R Rava said: (Feb 9, 2016) What is mica? How do mica high energy store?

 Ashwini Bhandare said: (Jul 22, 2016) Mica is the one of the type of capacitor. It consists low tolerance Hence it's energy is large, also it gives accurate value.

 Astha Tanya said: (Oct 20, 2016) What does capacitor do?

 Satyam Upadhyay said: (Nov 11, 2016) @Astha. A capacitor (originally known as a condenser) is a passive two-terminal electrical component used to temporarily store electrical energy in an electric field.

 Dharmaraj said: (Feb 13, 2017) Free space permittivity e0 - 8.85 * 10^-12 f/m.

 Yoby said: (Mar 6, 2017) What the difference between mica & plastic?

 Vivek said: (May 31, 2017) Permittivity-: ability of a substance to store electrical energy in an electric field. Mica-:they have great high-frequency properties due to low resistive and inductive losses, and are very stable over time.

 Naresh said: (Nov 24, 2017) What is the difference between mica and plastic?

 Priti said: (Apr 16, 2018) Here, E=1/2cv^2.

 Krishna Chetri said: (Jun 21, 2018) What actually mica is?

 Sireesha said: (Jul 22, 2018) Any material occurring mineral that based on a collection of silicate minerals and composed of varying amounts of potassium iron, aluminium, magnesium and water is mica in capacitor it acts as an insulator.

 Saikiran said: (Jul 27, 2018) Mica has highest dielectric strength among all materials. Dielectric strength is directly prorpotional to permittivity. So, highest dielectric strength means it can strore high amount of energy.

 Bhargavi said: (Dec 4, 2019) Is it produce only the electric field? Right. It does not produce magnetic field right.

 Kavya Bharti said: (Dec 28, 2019) What is work of capacitor?

 Vaibhav said: (Feb 2, 2020) @Kavya Bharti. To store energy in an electric form (charge).
