Learning Outcomes

p>On successful completion of this module, the student will be able to:

  • Understand the concept of ideal basic circuit elements, i.e. resistors, capacitors, inductors and voltage/current sources, and their respective current –voltage, voltage-current and energy relationships for dc and ac analysis.
  • Understand Ohm’s law and the Kirchhoff’s voltage and current laws (KVL and KCL) and therefore understand and apply the nodal and mesh methods to analyze circuits.
  • Understand the concepts and approaches of the circuit theorems (Thevenin and Norton equivalent circuits, source transformations, and superposition) and apply them to linear circuits for dc and ac analysis.
  • Develop and solve the differential equation for the transient response of RL and RC circuits.
  • Understand the sinusoidal steady-state analysis methods in time and frequency domains using the phasor concept with complex and diagram representations and understand the concepts of impedance, reactance, admittance and susceptance, and perform power calculations and und understand three phase power distribution.
