The formula that relates power, voltage, and resistance is derived from Ohm\u2019s Law and the basic power equation. Power PP can be calculated using the formula P=V\u00d7IP = V \\times I, where VV is voltage and II is current. Substituting Ohm\u2019s Law I=VRI = \\frac{V}{R} into the power equation gives P=V2RP = \\frac{V^2}{R}.<\/p>\n\n\n\n<p>In this case, the question provides the amount of power consumed by the resistor and the voltage across it. Using the formula P=V2RP = \\frac{V^2}{R}, one can rearrange it to solve for resistance by multiplying both sides by RR and then dividing both sides by PP, leading to R=V2PR = \\frac{V^2}{P}.<\/p>\n\n\n\n<p>Substituting the given values of voltage (100 volts) and power (180 watts) into the formula gives R=1002180R = \\frac{100^2}{180}, which simplifies to R=10000180R = \\frac{10000}{180}. The result is approximately 55.56 ohms. This value represents the amount of resistance required to limit the current flow so that the power delivered stays at 180 watts with the applied voltage of 100 volts.<\/p>\n\n\n\n<p>Understanding this concept is crucial in designing and analyzing electric circuits to ensure components are not damaged by excess current or power.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A power of 180 WW is delivered to a certain resistor when the applied voltage is 100 V The correct answer and explanation is: To find the resistance of the resistor, use the power formula: P=V2RP = \\frac{V^2}{R} Where: Given:Power P=180\u2009WP = 180 \\, \\text{W}Voltage V=100\u2009VV = 100 \\, \\text{V} Substitute the known values into [&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-34334","post","type-post","status-publish","format-standard","hentry","category-quiz-questions"],"_links":{"self":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/34334","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=34334"}],"version-history":[{"count":1,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/34334\/revisions"}],"predecessor-version":[{"id":34336,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/34334\/revisions\/34336"}],"wp:attachment":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/media?parent=34334"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/categories?post=34334"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/tags?post=34334"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
