


To introduce ac waveforms, the sine and cosine function and the phasor with relation to amplitude, frequency, phase and time.
To show how phasor addition/ subtraction requires complex number manipulation. To determine the equations for inductive and capacitive reactance and hence
impedance. To analyse series and parallel R,L and C circuits for single frequency sinusoidal excitation.
Develop a broad knowledge and skills to deal with diverse technological systems that exist in electromechanics and a detailed understanding of the range of tools
and techniques available to support this process.
Develop a general understanding of the relationships and interactions between the various components in an electromechanical system.
Develop and use a limited range of core theories and a range of principles and concepts, techniques and practices in the domain of electromechanics.
Acquire an outline knowledge and understanding of the fundamental uses of electromechanics in the context of current research for use in diverse areas of power
generation
