Amount of current to be collected.<\/p>\n<p>A commutator is a device used in electric motors and generators to reverse the current in the rotor windings. It consists of a series of copper segments insulated from each other and mounted on a rotating shaft. The segments are connected to the rotor windings, and brushes made of carbon or graphite are pressed against the segments to collect the current.<\/p>\n<p>The number of brushes in a commutator depends on the amount of current to be collected. The more current that needs to be collected, the more brushes are required. This is because the brushes need to be able to carry the current without overheating.<\/p>\n<p>The other options are not correct. The speed of the armature does not affect the number of brushes in a commutator. The type of winding does not affect the number of brushes in a commutator. The voltage does not affect the number of brushes in a commutator.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;Speed of armature&#8221; option2=&#8221;Type of winding&#8221; option3=&#8221;Voltage&#8221; option4=&#8221;Amount of current to be collected&#8221; correct=&#8221;option4&#8243;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[742],"tags":[],"class_list":["post-54725","post","type-post","status-publish","format-standard","hentry","category-d-c-generators","no-featured-image-padding"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>The number of brushes in a commutator depends on<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/exam.pscnotes.com\/mcq\/the-number-of-brushes-in-a-commutator-depends-on\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"The number of brushes in a commutator depends on\" \/>\n<meta property=\"og:description\" content=\"[amp_mcq option1=&#8221;Speed of armature&#8221; option2=&#8221;Type of winding&#8221; option3=&#8221;Voltage&#8221; option4=&#8221;Amount of current to be collected&#8221; correct=&#8221;option4&#8243;]\" \/>\n<meta property=\"og:url\" content=\"https:\/\/exam.pscnotes.com\/mcq\/the-number-of-brushes-in-a-commutator-depends-on\/\" \/>\n<meta property=\"og:site_name\" content=\"MCQ and Quiz for Exams\" \/>\n<meta property=\"article:published_time\" content=\"2024-04-16T00:15:05+00:00\" \/>\n<meta name=\"author\" content=\"rawan239\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<meta name=\"twitter:label1\" content=\"Written by\" \/>\n\t<meta name=\"twitter:data1\" content=\"rawan239\" \/>\n\t<meta name=\"twitter:label2\" content=\"Est. reading time\" \/>\n\t<meta name=\"twitter:data2\" content=\"1 minute\" \/>\n<!-- \/ Yoast SEO Premium plugin. -->","yoast_head_json":{"title":"The number of brushes in a commutator depends on","robots":{"index":"index","follow":"follow","max-snippet":"max-snippet:-1","max-image-preview":"max-image-preview:large","max-video-preview":"max-video-preview:-1"},"canonical":"https:\/\/exam.pscnotes.com\/mcq\/the-number-of-brushes-in-a-commutator-depends-on\/","og_locale":"en_US","og_type":"article","og_title":"The number of brushes in a commutator depends on","og_description":"[amp_mcq option1=&#8221;Speed of armature&#8221; option2=&#8221;Type of winding&#8221; option3=&#8221;Voltage&#8221; option4=&#8221;Amount of current to be collected&#8221; correct=&#8221;option4&#8243;]","og_url":"https:\/\/exam.pscnotes.com\/mcq\/the-number-of-brushes-in-a-commutator-depends-on\/","og_site_name":"MCQ and Quiz for Exams","article_published_time":"2024-04-16T00:15:05+00:00","author":"rawan239","twitter_card":"summary_large_image","twitter_misc":{"Written by":"rawan239","Est. reading time":"1 minute"},"schema":{"@context":"https:\/\/schema.org","@graph":[{"@type":"WebPage","@id":"https:\/\/exam.pscnotes.com\/mcq\/the-number-of-brushes-in-a-commutator-depends-on\/","url":"https:\/\/exam.pscnotes.com\/mcq\/the-number-of-brushes-in-a-commutator-depends-on\/","name":"The number of brushes in a commutator depends on","isPartOf":{"@id":"https:\/\/exam.pscnotes.com\/mcq\/#website"},"datePublished":"2024-04-16T00:15:05+00:00","dateModified":"2024-04-16T00:15:05+00:00","author":{"@id":"https:\/\/exam.pscnotes.com\/mcq\/#\/schema\/person\/5807dafeb27d2ec82344d6cbd6c3d209"},"breadcrumb":{"@id":"https:\/\/exam.pscnotes.com\/mcq\/the-number-of-brushes-in-a-commutator-depends-on\/#breadcrumb"},"inLanguage":"en-US","potentialAction":[{"@type":"ReadAction","target":["https:\/\/exam.pscnotes.com\/mcq\/the-number-of-brushes-in-a-commutator-depends-on\/"]}]},{"@type":"BreadcrumbList","@id":"https:\/\/exam.pscnotes.com\/mcq\/the-number-of-brushes-in-a-commutator-depends-on\/#breadcrumb","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https:\/\/exam.pscnotes.com\/mcq\/"},{"@type":"ListItem","position":2,"name":"mcq","item":"https:\/\/exam.pscnotes.com\/mcq\/category\/mcq\/"},{"@type":"ListItem","position":3,"name":"Electrical engineering","item":"https:\/\/exam.pscnotes.com\/mcq\/category\/mcq\/electrical-engineering\/"},{"@type":"ListItem","position":4,"name":"D.c.
