Analyze advanced concepts of direct and alternating current (DC & AC) and expand the knowledge of electrical circuitry. Various equipment will be studied that converts AC to DC and also that inverts DC to AC. The effects of varying frequency on AC filter circuits will be explored through labs. The usage of various voltage regulators will be also be covered. IET 5 expands on concepts learned in IET 1, IET 2, and IET 3 and will continue to be expanded upon in IET 6.
