The Revision series is designed for all JEE & NEET aspirants to provide quick revision of all the chapters of Class 11th & 12th with important key concepts. The revision videos help you make the best use of your limited time left for revision. It is especially time-saving for all students who are going to appear for 12th Board. When you don’t have time to go through chapter notes in detail, learn and revise most important key concepts and formulae here.

Here is the Revision of Electrostatics Chapter with important key concepts.

  1. Coulomb’s Law, Properties of Electric Charge
  2. Electric Field Intensity 
  3. Electric flux and Gauss’s Law
  4. Work done by Electrostatic Force
  5. Equipotential Surface
  6. Electric Dipole and Dipole Moment
  7. Conductors and its properties
  8. Faraday Cage, Conductors with Cavity, Parallel Conducting Plates, Electrostatic Pressure, Energy Density

Electric Charges and Fields, Coulomb’s Law, Properties of Electric Charge, Charging by Friction/Conduction & Induction.

Get to know about the Electric Charge and Fields by Saransh Gupta Sir. Here he will discuss about Coulomb’s Law of Electrostatics, Properties of Electric Charge, charging by induction, quantisation of charge, quantisation of charge, conservation of charge.

 

Electric fields, Electric Field Intensity, EFI Due to System of Point Charges, Motion of Charged Particle in Electric Field.

Get to learn about Electric Field Intensity and its Variations like Electric Field Intensity due to System of Point Charges, Variation of Electric Field Intensity on the Line Joining Two Point Charges, Electric Field Intensity on Perpendicular Bisector of Line Joining Two Point Charges , Electric Field Intensity on axis of Uniformly Charged Ring, Electric Field Intensity Due to Uniformly Charged Thin Straight Wire, Electric Field Intensity Due to Uniformly Charged Infinite Long Wire, Electric Field Intensity Due to Uniformly Charged Semi Infinite Long Wire, Electric Field Intensity Due to Uniformly Charged Semi Circular Arc, Electric Field Intensity on Axis of Uniformly Charged Disc, Electric Field Lines and Its Properties, Motion of Charged Particle in Electric Field.

 

Electric flux and Gauss’s Law, Electric field Intensity, Electric field due to infinite line charge, determine Flux

EFI due to Uniformly Charged Thin Spherical Shell, EFI due to Uniformly Charged Solid Sphere, Determine electric field intensity, EFI due to Infinite Line Charge (Uniformly Charged), EFI due to infinitely Long Uniformly Charged Cylindrical Shell, EFI due to infinite Long Uniformly Charged Cylindrical Shell

In this video you will learn about Electric Flux and Gauss’s Law. In electrostatics, the primary goal of Gauss’s law is to find the electric field for a given charge distribution, enclosed by a closed surface. Here you learn to determine flux and electric field intensity in various variants.

 

 

Work done by Electrostatic Force, Application of Work Energy Theorem, Potential Energy, electrostatic potential and capacitance Inside a field

Have you ever wondered how energy is stored in your watch’s cells? And what are the main principle behind it? Well, an electrostatic force is a force produced by stationary electric charges or fields. In this Video, you will learn everything about the electrostatic potential inside a field, the amount of work needs to move a unit positive charge from one initial point to any specified point without producing any acceleration is known as Electrostatic Potential (or also known as Electric Potential and Electric Field Potential).

Equipotential Surface, Calculation of Electric Potential from Electric Field Intensity

An equipotential surface is one where the potential is same at every point on the surface. Watch the video to learn in detail. Here are some topics that are discussed in the video:

 

Electric Dipole and Dipole Moment

Here you will get to know about Electric Dipole and Dipole Moment. Dipole moments are applied to the distribution of electrons between two bonded atoms. The existence of a dipole moment is the difference between polar and non-polar bonds. Molecules with a net dipole moment are polar molecules. If the net dipole moment is zero or very, very small, the bond and molecule are considered to be non-polar. Atoms that have similar electronegativity values tend to form chemical bonds with a very small dipole moment. Watch out the video to learn in detail.

 

Conductors and its properties

How often you have experienced a feeling of electric shock while opening the window of your car or coming in contact with wires in wet condition? Isn’t that a bit terrifying? But, why is that? Why don’t you get similar experiences with wooden materials? It is because they are insulators. The reason you get a shock is that there occurs a flow of electrons from one body to another when they come in contact via rubbing or moving against each other. Shock is basically a mini feeling of current passing through your body. So now, let us look at these concepts in more detail in this video by Saransh Gupta Sir.

 

Faraday Cage, Conductors with Cavity, Parallel Conducting Plates, Electrostatic Pressure, Energy Density, Effect of Medium

How do conductors actually conduct electricity? What do they have that the insulators do not? Have you ever wondered about these things? We have already read enough about conductors, insulators and more. This is the last part of Electrostatics Revision. Where Saransh sir covers concept of electrostatics of conductors. As You already know that capacitors can store electric charges. But, do you know how is the energy stored in a capacitor? And how much energy a capacitor can hold? Here we will study about the energy stored in a capacitor. We will see how much heat we can get out of a combination of capacitors in this video. Also get to know about parallel conducting plates, Faraday cage in detail in this video.
