The output from the regulated power supply may be alternating or unidirectional, but is nearly always DC (direct current). [1] The type of stabilization used may be restricted to ensuring that the output remains within certain limits under various load conditions, or it may also include compensation for variations in its own supply source.
Alternating current is any current that reverses direction repeatedly; almost always this takes the form of a sine wave. [46]: 206–07 Alternating current thus pulses back and forth within a conductor without the charge moving any net distance over time. The time-averaged value of an alternating current is zero, but it delivers energy in first ...
[26] [27] Again in 2022, a new controversy started when both CBSE and NCERT removed topics regarding Islamic Empires in the class 12 history textbook and chapters like “Challenges to Democracy” in the class 10 political science subject and many others, saying it is necessary to reduce syllabus to reduce examination pressure on students by ...
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 period is called a cycle). "Alternating current" most commonly refers to power distribution, but a wide range of other applications are technically ...
From Class 11 syllabus, chapters like Central Islamic Lands, Confrontation of cultures, and The Industrial Revolution have been removed. Apart from this, from Class 12 civics book Politics in Indian since Independence, chapters like Rise of popular movements, ‘Era of one-party dominance’ have been removed.
Many other combinations of voltage and utility frequency were formerly used, with frequencies between 25 Hz and 133 Hz and voltages from 100 V to 250 V. Direct current (DC) has been displaced by alternating current (AC) in public power systems, but DC was used especially in some city areas to the end of the 20th century.
Alternating current, a type of electric current AC power, a net transfer of energy over a complete cycle of the alternating current waveform; Asphalt concrete, a type of road or path surfacing; Average cost, in economics; Axiom of choice, a mathematical concept in set theory; A US Navy hull classification symbol: Collier (AC)
The term can also refer to a class of electrical machinery that is ... the input and output is alternating or direct current. [1] DC power conversion ... 0-12-088757 ...
