[amp_mcq option1=”Consumes some power on average” option2=”Does not take power at all from a line” option3=”Takes power from the line during some part of the cycle and then returns back to it during other part of the cycle” option4=”None of the above” correct=”option3″]<\/p>\n
The correct answer is: C. Takes power from the line during some part of the cycle and then returns back to it during other part of the cycle.<\/strong><\/p>\n A pure inductive circuit does not consume any power on average. This is because the current in an inductive circuit is always lagging behind the voltage by 90 degrees. This means that the power factor of an inductive circuit is always less than 1.<\/p>\n When an inductive circuit is connected to a power source, it will take power from the line during the first half of the cycle. However, during the second half of the cycle, the current will flow in the opposite direction and the circuit will return power to the line.<\/p>\n The net power consumption of a pure inductive circuit is therefore zero. However, the circuit will still draw current from the line, which can cause problems for other devices on the same circuit.<\/p>\n Here is a more detailed explanation of each option:<\/p>\n [amp_mcq option1=”Consumes some power on average” option2=”Does not take power at all from a line” option3=”Takes power from the line during some part of the cycle and then returns back to it during other part of the cycle” option4=”None of the above” correct=”option3″]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[739],"tags":[],"class_list":["post-58642","post","type-post","status-publish","format-standard","hentry","category-a-c-fundamentals-circuits-and-circuit-theory","no-featured-image-padding"],"yoast_head":"\n\n
