Tham khảo tài liệu 'unit 4: điện năng', kỹ thuật - công nghệ, điện - điện tử phục vụ nhu cầu học tập, nghiên cứu và làm việc hiệu quả | ELECTRICAL ENERGY ELECTRIC CIRCUIT MAIN POINTS ENERGY ELECTRICAL ENERGY ELECTRIC CIRCUIT ENERGY Energy: the capacity to do work (or produce heat). Kinetic energy: the energy of motion. Potential energy: the energy of position; stored energy. Kinetic energy Thermal energy: submicroscopic particles in motion. Mechanical energy: macroscopic objects in motion. Electrical energy: movement of electrons through a conductor. Sound energy: compression/expansion of spaces between molecules. Potential energy Chemical potential energy: position of electrons relative to atomic nuclei in bound atoms. Gravitational energy: position of an object in a gravitational field. Electrostatic energy: relative position of charged particles. ELECTRICAL ENERGY Electrical Energy - The energy associated with electric charges and their movements Electric Power - The amount of energy produced per second. The power produced by an electric current. KINDS OF CIRCUITS SERIES PARALLEL Req = R1 + R2 + R3 1 / Req = 1 / R1 + 1 / R2 + 1 / R3 + . Ohm's law the potential difference or voltage drop (V) between the ends of a conductor and the current (I) flowing through the conductor are proportional at a given temperature: V = I R Kirchhoff's current law i1 + i4 = i2 + i3 Kirchhoff's voltage law v1 + v2 + v3 + v4 = 0 REFERENCE | ELECTRICAL ENERGY ELECTRIC CIRCUIT MAIN POINTS ENERGY ELECTRICAL ENERGY ELECTRIC CIRCUIT ENERGY Energy: the capacity to do work (or produce heat).
