Electrical and Electronic Principles, 2, Second Edition covers the syllabus requirements of BTEC Unit U86/329, including the principles of control systems and elements of data transmission. The book first tackles series and parallel circuits, electrical networks, and capacitors and capacitance. Discussions focus on flux density, electric force, permittivity, Kirchhoff's laws, superposition theorem, arrangement of resistors, internal resistance, and powers in a circuit. The text then takes a look at capacitors in circuit, magnetism and magnetization, electromagnetic induction, and alternating voltages and currents. Topics include phasors, addition and subtraction of sine waves, generator and motor principles, inductance of a coil, energy stored in an inductance, magnetization curves, magnetic hysteresis, and practical capacitor construction. The manuscript ponders on the elements of data transmission, principles of control systems, and instruments and measurements. Concerns include moving iron meter, measurement of resistance, automatic and temperature control, transmission methods, and channel capacity and encoding. The text is a vital reference for electrical and electronics engineers.
