NEET

The chemical bonds can be primary or strong bonds such as ionic, covalent, and metallic bonds. It can also be the secondary or weak bonds like hydrogen bonding, London dispersion force, and dipole interactions.

It is the bond that holds the ions, atoms or molecules to form stable substances, compounds and larger structures.

In Chemistry, the bonds are of four types - Covalent bond, Ionic bond, Hydrogen bond, and Metallic bond.

This chapter covers the concepts of potential, capacitors, and potential energy. It is considered as one of the easy chapter of the class 12 Physics.

It is the farad (F). The name came from Michael Faraday. SI Unit of Capacitance means the ability of a system to store an electric charge. One farad is the capacitance of a device that needs one coulomb of charge to provide one volt potential difference across it. Mathematically, it is represented by - 1 Farad = 1 Coulomb/Volt. 

In JEE Main Physics, electric potential and capacitance chapter has a weightage of 3% to 6%. You can expect around 1 or 2 questions from this chapter which carries 4 to 8 marks.

In NEET Physics exam, the chapter electric potential and capacitance carries a weightage of 2% to 5%, which means you can expect one question out of 45 questions.

The ability to do work on a charge is called the electric potential and the ability to store charge is termed as the capacitance.

The different types of sets covered in this chapter are - Empty Set, Singleton Set, Finite Set, Infinite Set, Equal Sets, Equivalent Sets, Subset, Proper Subset, Universal Set, Power Set, and Disjoint Sets.
