2006 - Present
This course unit offered by the department of physics to both physical science students as well as biological science students. This covers the fundamental aspects of Theories of Alternating Current such as Reactance, r.m.s Voltages and Currents, Power Dissipation, Phase shifts, resonance and filters (frequency).
Basic characteristics of Modern Sound Systems also introduced at this level.
