AC CircuitsLaajuus (3 cr)

Objective

• The student understands the representation of AC quantities both in the time domain and as complex phasors. They understand the significance of inductors and capacitors in electrical engineering and can calculate their impedance and admittance. The student is capable of solving AC circuit problems using complex representations.
• The student understands the concepts of apparent power, active power, and reactive power and can calculate a component's or system's apparent power using complex current and voltage values.
• The student can use an oscilloscope and a function generator in basic AC measurements and can measure a circuit's or system's frequency response using these instruments.
• The student can design first-order filters and analyze their responses based on the transfer function.
