In many countries like the United States, the average residential electricity cost is around <strong>$0.17 per kWh<\/strong>, which is <strong>17 cents per kWh<\/strong>.<\/p>\n\n\n\n<p>Multiply the energy used by the cost per kWh:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>1.68 kWh \u00d7 17 cents = <strong>28.56 cents<\/strong><\/li>\n<\/ul>\n\n\n\n<p>This rounds to approximately <strong>28 cents<\/strong> to run the 10-watt light for one week.<\/p>\n\n\n\n<p>This result shows how energy-efficient a 10-watt light is. Such lights are often LED bulbs. Running one for an entire week nonstop costs less than a single coin. This low cost is one of the reasons LED lights are so popular. They provide good brightness while keeping electricity bills down. If many lights are used, the total cost can still grow, so using efficient lights and turning them off when not needed helps save money and energy.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>what will be the approximate cost in cents of running a 10 watt light for one week The correct answer and explanation is: Correct Answer:Approximate cost in cents: 28 cents To calculate the cost of running a 10-watt light for one week, we begin by determining how much energy it consumes over that time and [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-29247","post","type-post","status-publish","format-standard","hentry","category-quiz-questions"],"_links":{"self":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/29247","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/comments?post=29247"}],"version-history":[{"count":1,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/29247\/revisions"}],"predecessor-version":[{"id":29252,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/29247\/revisions\/29252"}],"wp:attachment":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/media?parent=29247"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/categories?post=29247"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/tags?post=29247"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
