Alternating Current Circuit,resistor, capacitor, and coil, and learn the analysis method to determine the current. We also learn the characteristics of various types of filter from the frequency response. The advantage of using the complex electric power, which is composed of the effective electric power and reactive electric power, is introduced.

Conductors and Dielectric Materials, field is applied to a conductor, the electric field strength is zero inside the conductor due to induced electric charges on the surface. Conductors are equipotential. When an external electric field is applied to a dielectric material, the electric field penetrates the dielectric material, althoug

Current and Magnetic Phenomena,caused by a magnetic distortion in space that is produced by other currents and this distortion is called magnetic field. The magnetic flux density is used as a quantity that expresses the strength of the magnetic field. The local magnetic flux density produced by currents is described by the Biot-S

Superconductors and Magnetic Materials,en a superconductor is placed in a magnetic flux density, the magnetic flux density is zero inside the superconductor due to a current flowing on its surface, similarly to electrical phenomena in a conductor in an electric field. On the other hand, the internal magnetic flux density is increased due
