[amp_mcq option1=”current” option2=”voltage” option3=”impedance” option4=”none of the above” correct=”option1″]<\/p>\n
The correct answer is: A. current<\/strong><\/p>\n A capacitor is a circuit component that stores electrical energy in an electric field. It does this by opposing changes in the current flowing through it. When current flows into a capacitor, it charges the plates of the capacitor. When the current stops flowing, the capacitor discharges, releasing the stored energy.<\/p>\n Capacitors are used in a variety of electronic circuits, including filters, amplifiers, and oscillators. They are also used in power supplies to smooth out the output voltage.<\/p>\n Option B is incorrect because voltage is the difference in electrical potential between two points. It is not a circuit component.<\/p>\n Option C is incorrect because impedance is the total opposition to current flow in an electric circuit. It is a combination of resistance, capacitance, and inductance.<\/p>\n Option D is incorrect because capacitors do oppose changes in current.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”current” option2=”voltage” option3=”impedance” option4=”none of the above” correct=”option1″]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[971],"tags":[],"class_list":["post-46834","post","type-post","status-publish","format-standard","hentry","category-electrostatics","no-featured-image-padding"],"yoast_head":"\n
