In both directions.<\/p>\n<p>Ward Leonard control is a method of speed control for electric motors that uses a DC motor, a variable voltage DC power supply, and a controller. The DC motor is the load, and the variable voltage DC power supply is used to control the speed of the motor. The controller is used to regulate the voltage of the power supply, which in turn controls the speed of the motor.<\/p>\n<p>Ward Leonard control can be used to control the speed of a motor in both directions. To control the speed of the motor in the forward direction, the voltage of the power supply is increased. To control the speed of the motor in the reverse direction, the voltage of the power supply is decreased.<\/p>\n<p>The Ward Leonard control method is a versatile and efficient method of speed control for electric motors. It is widely used in a variety of applications, including industrial machinery, elevators, and cranes.<\/p>\n<p>Here is a brief explanation of each option:<\/p>\n<ul>\n<li>Option A: In one direction. This is incorrect because Ward Leonard control can be used to control the speed of a motor in both directions.<\/li>\n<li>Option B: In both directions. This is the correct answer because Ward Leonard control can be used to control the speed of a motor in both directions.<\/li>\n<li>Option C: Below normal speed only. This is incorrect because Ward Leonard control can be used to control the speed of a motor above or below normal speed.<\/li>\n<li>Option D: Above normal speed only. This is incorrect because Ward Leonard control can be used to control the speed of a motor above or below normal speed.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;In one direction&#8221; option2=&#8221;In both directions&#8221; option3=&#8221;Below normal speed only&#8221; option4=&#8221;Above normal speed only&#8221; correct=&#8221;option2&#8243;]<\/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":[],"class_list":["post-47691","post","type-post","status-publish","format-standard","hentry","category-d-c-motors","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>Speed control by Ward Leonard method gives uniform speed variation<\/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\/speed-control-by-ward-leonard-method-gives-uniform-speed-variation\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Speed control by Ward Leonard method gives uniform speed variation\" \/>\n<meta property=\"og:description\" content=\"[amp_mcq option1=&#8221;In one direction&#8221; option2=&#8221;In both directions&#8221; option3=&#8221;Below normal speed only&#8221; option4=&#8221;Above normal speed only&#8221; correct=&#8221;option2&#8243;]\" \/>\n<meta property=\"og:url\" content=\"https:\/\/exam.pscnotes.com\/mcq\/speed-control-by-ward-leonard-method-gives-uniform-speed-variation\/\" \/>\n<meta property=\"og:site_name\" content=\"MCQ and Quiz for Exams\" \/>\n<meta property=\"article:published_time\" content=\"2024-04-15T22:30:25+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=\"2 minutes\" \/>\n<!-- \/ Yoast SEO Premium plugin. -->","yoast_head_json":{"title":"Speed control by Ward Leonard method gives uniform speed variation","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\/speed-control-by-ward-leonard-method-gives-uniform-speed-variation\/","og_locale":"en_US","og_type":"article","og_title":"Speed control by Ward Leonard method gives uniform speed variation","og_description":"[amp_mcq option1=&#8221;In one direction&#8221; option2=&#8221;In both directions&#8221; option3=&#8221;Below normal speed only&#8221; option4=&#8221;Above normal speed only&#8221; correct=&#8221;option2&#8243;]","og_url":"https:\/\/exam.pscnotes.com\/mcq\/speed-control-by-ward-leonard-method-gives-uniform-speed-variation\/","og_site_name":"MCQ and Quiz for Exams","article_published_time":"2024-04-15T22:30:25+00:00","author":"rawan239","twitter_card":"summary_large_image","twitter_misc":{"Written by":"rawan239","Est. reading time":"2 minutes"},"schema":{"@context":"https:\/\/schema.org","@graph":[{"@type":"WebPage","@id":"https:\/\/exam.pscnotes.com\/mcq\/speed-control-by-ward-leonard-method-gives-uniform-speed-variation\/","url":"https:\/\/exam.pscnotes.com\/mcq\/speed-control-by-ward-leonard-method-gives-uniform-speed-variation\/","name":"Speed control by Ward Leonard method gives uniform speed variation","isPartOf":{"@id":"https:\/\/exam.pscnotes.com\/mcq\/#website"},"datePublished":"2024-04-15T22:30:25+00:00","dateModified":"2024-04-15T22:30:25+00:00","author":{"@id":"https:\/\/exam.pscnotes.com\/mcq\/#\/schema\/person\/5807dafeb27d2ec82344d6cbd6c3d209"},"breadcrumb":{"@id":"https:\/\/exam.pscnotes.com\/mcq\/speed-control-by-ward-leonard-method-gives-uniform-speed-variation\/#breadcrumb"},"inLanguage":"en-US","potentialAction":[{"@type":"ReadAction","target":["https:\/\/exam.pscnotes.com\/mcq\/speed-control-by-ward-leonard-method-gives-uniform-speed-variation\/"]}]},{"@type":"BreadcrumbList","@id":"https:\/\/exam.pscnotes.com\/mcq\/speed-control-by-ward-leonard-method-gives-uniform-speed-variation\/#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.
