The few minor issues are marked above. The missing elephant in this zoo is a lack of an article on synchronous generators, arguably the most important variety. Currently, the information is a part of the Alternator, which makes for a confusing name and thus is hard to find/link to (for example, until today the redirect Synchronous generator pointed to Synchronization (alternating current), which contains next to zero information on the actual generators). Permanent magnet asynchronous generator does not appear to be covered anywhere. Synchronous machine is a redirect to Synchronous motor, even though it usually used to describe a generator.
My suggestions:
Split Synchronous generator from Alternator. Leave alternator to describe a generic AC generator (this is currently a redirect). This is a big change, and I am hereby looking for opinions.
Fix other problems above by removing paragraphs. providing links and clarifications.
Expand the template {{Electric machines}} along the lines of the list above.
electrical polarity, which is defined as the property of an electrified body or apparatus to have electrical charges of positive and negative signs at opposite ends or on two electrodes ([4], a patent)
Correct answer to the question "electrical polarity refers to ..." in the "Grantham's FCC License Study Guide" ([5])
"Polarity-1. A condition by which the direction of current can be determined in an electrical circuit (usually batteries and other direct-voltage sources). 2. Having two opposite charges, one positive and one negative. 4. The condition of positiveness or negativeness in an electrical circuit. 5. The positive and negative orientation of a signal or power source. 6. Any condition in which there are two opposing voltage levels or charges, such as positive and negative." Graf, 1999, Modern Dictionary of Electronics
"DC is current that travels in one direction only. ... DC is also said to have constant polarity; meaning it doesn't change from positive to negative and vice versa. ... AC has electron flow in both directions, alternating from forward to backward. It also has changes in polarity. DEFINITION: Polarity is a positive or negative electric charge" The Complete Idiot's Guide to Electronics 101, 2011
One of your project's articles has been selected for improvement!
Hello, Please note that Volt, which is within this project's scope, has been selected as one of the Articles for improvement. The article is scheduled to appear on Wikipedia's Community portal in the "Articles for improvement" section for one week, beginning today. Everyone is encouraged to collaborate to improve the article. Thanks, and happy editing! Delivered by — MusikBottalk00:05, 2 December 2024 (UTC) on behalf of the AFI team[reply]
