Class 12 Physics chapter 1 Electric charges and fields handwritten notes
- Electric charges: conservation of charge; Coulomb's law forces between two point charges; forces between multiple charges; the superposition principle; and continuous charge distribution
- Electric field: electric field due to a point charge, electric field lines, electric dipole, electric field due to a dipole, torque on a dipole in a uniform electric field
- Electric flux, Gauss's law, and its applications to find field are due to an infinitely long, uniformly charged straight wire, an infinitely charged plane sheet, and a uniformly charged thin spherical shell. Electric potential and its calculation for a point charge, an electric dipole, and a system of charges; Equipotential surfaces, the electrical potential energy of a system of two point charges in an electrostatic field
- Conductors and insulators, Dielectrics and electric polarization, capacitors, combinations of capacitors in series and in parallel, capacitance of a parallel plate capacitor with and without dielectric medium between the plates, energy stored in a capacitor
Chapter 1: Electric Charges and Fields
1. Electricity Fees
- Charge conservation
- Coulomb’s law of force between two point charges
- forces between multiple charges
- Superposition principle
- Continuous charge distribution
3. Electric flux, the statement of Gauss’s theorem, and its applications to finding field are due to an infinitely long straight wire, a uniformly charged infinite plane sheet, and a uniformly charged thin spherical shell (field inside and outside).

Electrostatics - study of forces, fields and potentials due to charges at rest.
Examples for static electricity are
- spark or hearing a crackle when we take off our synthetic clothes or sweater particularly in dry weather
- Sensation of an electric shock while opening the door of a car or holding the iron bar of a bus after sliding from our seat.
- Lightning
- A comb rubbed with hair attracts small pieces of paper etc.
Electric Charge
- Electric charge is the physical property of matter that causes it to experience a force when placed in
- an electromagnetic field.
- The two types of charges are positive and negative (Named by Benjamin Franklin)
- Like charges repels and unlike charges attracts.
- When amber rubbed with wool or silk cloth attracts light objects – discovered by Thales.
- Electroscope – device for charge detection
- It is a scalar quantity .
- SI unit of electric charge- coulomb (C)
- Charge of a proton is positive (1.602192 × 10-19 C)
- Charge of an electron is negative (-1.602192 × 10-19 C)
- Matter with equal number of electrons and protons are electrically neutral.
- Matter with excess number of electrons – negatively charged
- Matter with excess protons – positively charged.
- Substances which allow passage of charges .
- Eg : Metals, human body etc
- The charge transferred to a conductor is distributed over the entire surface of the conductor.
- Substances which does not allow passage of charges.
- Eg: plastic, rubber etc.
- The charge transferred to an insulator stays at the same place.
- The process of sharing charges with earth.
- Earthing provides a safety measure for electrical circuits and appliances.
- When two bodies are rubbed electrons are transferred from material with lower work function to material with higher work function.
- Work function – energy required to remove an electron from a metal surface.
- Body gains electrons- negatively charged
- Body which loses electron – positively charged.
- Positively charged body – mass decreases
- Negatively charged body – mass increases
- When a charged body is brought in to contact with an uncharged conductor, charge flows from the charged body to the uncharged body.
- This is used to charge a conductor.
- When a charged body is brought near to an uncharged conductor (without touching), that end of the uncharged conductor which is near to the charged body gets oppositely charged and the farther end is charged with the same type of charge.
