Electricity and Magnetism (A C Theory) (First Year/Second Year)

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.
