This back EMF is proportional to the speed of the motor, so at the instant of starting, when the motor is not moving, the back EMF is zero and the current is limited by the resistance of the windings.<\/p>\n<p>Option B is incorrect because a low resistance circuit would allow a large current to flow, which would cause the motor to overheat. Option C is incorrect because a capacitive circuit would block the flow of current, which would prevent the motor from starting. Option D is incorrect because the motor does behave like a circuit, albeit a highly resistive one.<\/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>At the instant of starting when a D.C. motor is put on supply, it behaves like<\/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\/at-the-instant-of-starting-when-a-d-c-motor-is-put-on-supply-it-behaves-like\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"At the instant of starting when a D.C. motor is put on supply, it behaves like\" \/>\n<meta property=\"og:description\" content=\"Join Our Telegram Channel Subscribe on YouTube\" \/>\n<meta property=\"og:url\" content=\"https:\/\/exam.pscnotes.com\/mcq\/at-the-instant-of-starting-when-a-d-c-motor-is-put-on-supply-it-behaves-like\/\" \/>\n<meta property=\"og:site_name\" content=\"MCQ and Quiz for Exams\" \/>\n<meta property=\"article:published_time\" content=\"2024-04-15T22:12:45+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":"At the instant of starting when a D.C. motor is put on supply, it behaves like","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\/at-the-instant-of-starting-when-a-d-c-motor-is-put-on-supply-it-behaves-like\/","og_locale":"en_US","og_type":"article","og_title":"At the instant of starting when a D.C. motor is put on supply, it behaves like","og_description":"Join Our Telegram Channel Subscribe on YouTube","og_url":"https:\/\/exam.pscnotes.com\/mcq\/at-the-instant-of-starting-when-a-d-c-motor-is-put-on-supply-it-behaves-like\/","og_site_name":"MCQ and Quiz for Exams","article_published_time":"2024-04-15T22:12:45+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\/at-the-instant-of-starting-when-a-d-c-motor-is-put-on-supply-it-behaves-like\/","url":"https:\/\/exam.pscnotes.com\/mcq\/at-the-instant-of-starting-when-a-d-c-motor-is-put-on-supply-it-behaves-like\/","name":"At the instant of starting when a D.C. motor is put on supply, it behaves like","isPartOf":{"@id":"https:\/\/exam.pscnotes.com\/mcq\/#website"},"datePublished":"2024-04-15T22:12:45+00:00","dateModified":"2024-04-15T22:12:45+00:00","author":{"@id":"https:\/\/exam.pscnotes.com\/mcq\/#\/schema\/person\/5807dafeb27d2ec82344d6cbd6c3d209"},"breadcrumb":{"@id":"https:\/\/exam.pscnotes.com\/mcq\/at-the-instant-of-starting-when-a-d-c-motor-is-put-on-supply-it-behaves-like\/#breadcrumb"},"inLanguage":"en-US","potentialAction":[{"@type":"ReadAction","target":["https:\/\/exam.pscnotes.com\/mcq\/at-the-instant-of-starting-when-a-d-c-motor-is-put-on-supply-it-behaves-like\/"]}]},{"@type":"BreadcrumbList","@id":"https:\/\/exam.pscnotes.com\/mcq\/at-the-instant-of-starting-when-a-d-c-motor-is-put-on-supply-it-behaves-like\/#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.
