    Study Notes

    Electric Charges

    • Electric charge is a fundamental property of matter
    • There are two types of electric charges: positive (+) and negative (-)
    • Like charges repel each other, while opposite charges attract each other

    Coulomb's Law

    • Coulomb's Law describes the electrostatic force between two point charges
    • The force is proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them
    • The force can be attractive or repulsive, depending on the sign of the charges

    Electric Field

    • Electric field is a vector field that surrounds charged particles
    • Electric field lines emerge from positive charges and enter negative charges
    • Electric field strength is measured in Newtons per Coulomb (N/C) or Volts per meter (V/m)

    Electric Potential

    • Electric potential, or voltage, is the potential energy per unit charge
    • Electric potential is measured in Volts (V)
    • Electric potential difference is the difference in electric potential between two points

    Electric Dipole

    • Electric dipole is a pair of equal and opposite charges separated by a small distance
    • Electric dipole moment is a measure of the strength of the dipole
    • Electric dipole moment is a vector quantity, measured in Coulomb-meters (C·m)

    Gauss's Law

    • Gauss's Law relates the distribution of electric charge to the resulting electric field
    • The total electric flux through a closed surface is proportional to the charge enclosed within the surface
    • Gauss's Law is a fundamental principle of electrostatics, used to calculate electric fields and potentials
