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
