Explain how alternating voltage can be generated using a rotating coil in a magnetic field.
Explain how alternating voltage can be generated using a rotating coil in a magnetic field.
Alternating voltage can be generated by rotating a coil in a magnetic field, which induces a varying magnetic flux. This varying flux induces an electromotive force (emf) in the coil, resulting in an alternating voltage across the coil's terminals.
What are the different alternating quantities mentioned in the text and how are they defined?
What are the different alternating quantities mentioned in the text and how are they defined?
The different alternating quantities mentioned in the text are instantaneous, RMS (Root Mean Square), and average values. Instantaneous value is the value of a quantity at any instant of time, RMS value is the square root of the average of the squares of the instantaneous values, and average value is the arithmetic mean of the instantaneous values over a complete cycle.
Define form factor and crest factor in the context of alternating quantities.
Define form factor and crest factor in the context of alternating quantities.
Form factor is the ratio of RMS value to the average value of an alternating quantity, while crest factor is the ratio of the peak value to the RMS value of an alternating quantity.
