These cables have resistance, and power is lost as heat according to the formula P_loss = I\u00b2 * R, where I is the current and R is the resistance of the cable. To minimize this power loss for a given amount of power being transmitted (P = V * I), the voltage (V) is stepped up to a very high level by transformers at the power station. This high voltage means the current (I) required to transmit the same power is much lower (I = P\/V). A lower current significantly reduces the power loss (I\u00b2R) in the transmission lines. At the receiving end, transformers step the voltage back down for safe use in homes and factories.<br \/>\n<\/section>\n<section id=\"pyq-additional-information\">\nWhile stepping up voltage does also reduce voltage drop (V_drop = I*R), the primary purpose of high-voltage transmission is the dramatic reduction in power loss, making long-distance transmission economically feasible. Transformers are essential for changing voltage levels efficiently in AC circuits.<br \/>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>Transformers are used in between the electric power stations and homes or factories in order to [amp_mcq option1=&#8221;minimize the power loss in transmission cables&#8221; option2=&#8221;minimize the voltage drop in transmission cables&#8221; option3=&#8221;minimize the current drop in the transmission cables&#8221; option4=&#8221;provide constant voltage at the user end&#8221; correct=&#8221;option1&#8243;] This question was previously asked in UPSC CAPF &#8230; <\/p>\n<p class=\"read-more-container\"><a title=\"Transformers are used in between the electric power stations and homes\" class=\"read-more button\" href=\"https:\/\/exam.pscnotes.com\/mcq\/transformers-are-used-in-between-the-electric-power-stations-and-homes\/#more-89400\">Detailed Solution<span class=\"screen-reader-text\">Transformers are used in between the electric power stations and homes<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1085],"tags":[1465,1201,1128],"class_list":["post-89400","post","type-post","status-publish","format-standard","hentry","category-upsc-capf","tag-1465","tag-electric-current","tag-physics","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>Transformers are used in between the electric power stations and homes<\/title>\n<meta name=\"description\" content=\"Transformers are used in between the electric power stations and homes or factories in order to minimize the power loss in transmission cables.
