The abbreviations AC and DC are often used to mean simply alternating and direct, respectively, as when they modify current or voltage. [ 1 ] [ 2 ] The usual waveform of alternating current in most electric power circuits is a sine wave , whose positive half-period corresponds with positive direction of the current and vice versa (the full ...
Air conditioning, often abbreviated as A/C (US) or air con (UK), [1] is the process of removing heat from an enclosed space to achieve a more comfortable interior temperature and in some cases also controlling the humidity of internal air.
Angle notation can easily describe leading and lagging current: . [1] In this equation, the value of theta is the important factor for leading and lagging current. As mentioned in the introduction above, leading or lagging current represents a time shift between the current and voltage sine curves, which is represented by the angle by which the curve is ahead or behind of where it would be ...
The concept of power dissipation in AC circuit is explained and illustrated with the example. For instance, a power factor of 0.68 means that only 68 percent of the total current supplied (in magnitude) is actually doing work; the remaining current does no work at the load. Power Factor is very important in Power sector substations.
An academic degree is a qualification awarded to a student upon successful completion of a course of study in higher education, usually at a college or university.These institutions often offer degrees at various levels, usually divided into undergraduate and postgraduate degrees.
To train as a building services engineer, the academic requirements are GCSEs (A-C) / Standard Grades (1-3) in Maths and Science, which are important in measurements, planning and theory. Employers will often want a degree in a branch of engineering, such as building environment engineering , electrical engineering or mechanical engineering.
A Certificate of Advanced Study (CAS), [1] also called an Advanced Certificate (AC), [2] [3] [4] Certificate of Advanced Graduate Study (CAGS), [5] or a Certificate of Advanced Professional Studies (CAPS), is a post-Master's academic certificate designed for professional and non traditional students, as well as practitioners who seek a continuing education program to enhance their professional ...
Degrees and diplomas, first grouped according to the corresponding Australian Qualifications Framework levels and ordered from lowest-to-highest, then in chronological order within those groups, [2] Fellowships then memberships of professional and academic bodies, Parliamentary and military designations. Full-stops are not usually used in ...
