When the motor is turned off, the current through the rheostat causes it to heat up. This heat energy is then used to slow down the motor.<\/p>\n<p>Option A is incorrect because the motor is not run as a generator during rheostatic braking. A generator converts mechanical energy into electrical energy, while a motor converts electrical energy into mechanical energy. During rheostatic braking, the motor is still converting electrical energy into mechanical energy, but the energy is being dissipated in the rheostat instead of being used to turn a load.<\/p>\n<p>Option B is incorrect because the motor is not reversed in direction during rheostatic braking. The direction of rotation of a DC series motor is determined by the polarity of the applied voltage. When the motor is turned off, the polarity of the applied voltage does not change, so the direction of rotation does not change either.<\/p>\n<p>Option D is incorrect because rheostatic braking is a real and effective way to slow down a DC series motor.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Join Our Telegram Channel Subscribe on YouTube<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[743],"tags":[],"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>During rheostatic braking of D.C. series motors<\/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\/during-rheostatic-braking-of-d-c-series-motors\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"During rheostatic braking of D.C. series motors\" \/>\n<meta property=\"og:description\" content=\"Join Our Telegram Channel Subscribe on YouTube\" \/>\n<meta property=\"og:url\" content=\"https:\/\/exam.pscnotes.com\/mcq\/during-rheostatic-braking-of-d-c-series-motors\/\" \/>\n<meta property=\"og:site_name\" content=\"MCQ and Quiz for Exams\" \/>\n<meta property=\"article:published_time\" content=\"2024-04-15T21:50:01+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":"During rheostatic braking of D.C. series motors","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\/during-rheostatic-braking-of-d-c-series-motors\/","og_locale":"en_US","og_type":"article","og_title":"During rheostatic braking of D.C. series motors","og_description":"Join Our Telegram Channel Subscribe on YouTube","og_url":"https:\/\/exam.pscnotes.com\/mcq\/during-rheostatic-braking-of-d-c-series-motors\/","og_site_name":"MCQ and Quiz for Exams","article_published_time":"2024-04-15T21:50:01+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\/during-rheostatic-braking-of-d-c-series-motors\/","url":"https:\/\/exam.pscnotes.com\/mcq\/during-rheostatic-braking-of-d-c-series-motors\/","name":"During rheostatic braking of D.C. series motors","isPartOf":{"@id":"https:\/\/exam.pscnotes.com\/mcq\/#website"},"datePublished":"2024-04-15T21:50:01+00:00","dateModified":"2024-04-15T21:50:01+00:00","author":{"@id":"https:\/\/exam.pscnotes.com\/mcq\/#\/schema\/person\/5807dafeb27d2ec82344d6cbd6c3d209"},"breadcrumb":{"@id":"https:\/\/exam.pscnotes.com\/mcq\/during-rheostatic-braking-of-d-c-series-motors\/#breadcrumb"},"inLanguage":"en-US","potentialAction":[{"@type":"ReadAction","target":["https:\/\/exam.pscnotes.com\/mcq\/during-rheostatic-braking-of-d-c-series-motors\/"]}]},{"@type":"BreadcrumbList","@id":"https:\/\/exam.pscnotes.com\/mcq\/during-rheostatic-braking-of-d-c-series-motors\/#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.
