OSNOVI ELEKTROTEHNIKE II

Passing the exam in this subject means that the student is able to: 1. Define the concept of a stationary magnetic field and the basic quantities that describe it; 2. Calculate magnetic flux density by applying the Biot-Savart and Amperes law; 3. Define Faradays law of electromagnetic induction, interpret the direction of the induced emf and distinguish between its static and dynamic components; 4. Define the concepts of self and mutual inductance and calculate inductance in typical cases (solenoid, toroidal winding, two-wire line, coaxial line); 5. Explain the need to introduce the concept of rotating vector, phasor and complex calculus in the analysis of linear AC circuits; 6. Define the concept of complex impedance and admittance, complex power; 7. Interpret symbols and conventions in magnetically coupled circuits and define an ideal transformer; 8. Define the concept of voltage and current resonance, Q factor, amplitude and phase characteristics; 9. Define a balanced three-phase circuit and understand the wye and delta connections; 10. Solve the linear AC circuit using elementary transformations, methods and theorems, both using the phasor diagram in simple cases and using complex calculus.
