The correct answer is: D. Electrolytic<\/strong><\/p>\n Explanation:<\/p>\n Capacitors are devices that store electrical energy in an electric field. They are made up of two conductive plates separated by an insulating material. The capacitance of a capacitor is measured in farads (F).<\/p>\n Air capacitors are the simplest type of capacitor. They are made up of two conductive plates separated by a layer of air. Air capacitors have a low capacitance and are not very efficient.<\/p>\n Paper capacitors are made up of two conductive plates separated by a layer of paper. Paper capacitors have a higher capacitance than air capacitors and are more efficient.<\/p>\n Mica capacitors are made up of two conductive plates separated by a layer of mica. Mica capacitors have a higher capacitance than paper capacitors and are more efficient.<\/p>\n Electrolytic capacitors are made up of two conductive plates separated by an insulating layer of aluminum oxide. Electrolytic capacitors have a very high capacitance and are very efficient. However, they are polarized and can only be used with DC voltage.<\/p>\n In conclusion, electrolytic capacitors are the only type of capacitor that can be used only for DC.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”Air” option2=”Paper” option3=”A.
