A tantárgy részletes tematikája
- ELECTRIC POTENTIAL: Potential energy associated with the electrostatic force. Electric potential difference (voltage) and electric potential. Equipotential surfaces. The electric potential of a point charge, a group of charges, a continuous charge distribution. Mathematical relationship between the electric field vector and the electric potential. Charged conductors in electrostatic equilibrium.
- CAPACITANCE AND DIELECTRICS: Capacitance. Parallel plate capacitor, cylindrical capacitor, spherical capacitor. Parallel and series combination of capacitors. Energy stored in a charged capacitor. The electric dipole in an external electric field: torque, potential energy. Dielectrics. Atomic dipole moments and the polarization vector. Electric susceptibility, relative dielectric constant. The electric displacement vector. Boundary conditions for the electric field vector and the displacement vector. Energy density of the electric field.
- CURRENT AND RESISTANCE. DIRECT CURRENT CIRCUITS: Electric current. Current density. Ohm's law. resistivity, conductivity, resistance. Power supplied by a battery. Power dissipated in a resistor. Parallel and series combination of resistors. Kirchhoff's rules. RC circuits: charging and discharging a capacitor.
- MAGNETIC FIELDS. SOURCES OF THE MAGNETIC FIELD: Magnetism. Magnetic field. Magnetic force on a moving charge. Applications: cyclotron, velocity selector. Magnetic force on a current-carrying conductor. Torque on a current loop. The magnetic dipole. The magnetic field strength. The permeability of free space. Analogy between electricity and magnetism (electricity: acts on charges, is created by charges; magnetism: acts on moving charges, is created by moving charges). The Biot-Savart law. Magnetic force between two parallel conductors. Ampere's law.
