[amp_mcq option1=”Alternating Current and Direct Current” option2=”A Rock Band from Australia” option3=”Average Current and Discharged Capacitor” option4=”Atlantic City and District of Columbia” correct=”option1″]<\/p>\n
The correct answer is: A. Alternating Current and Direct Current<\/p>\n
Alternating current (AC) is an electric current that reverses its direction periodically. Direct current (DC) is an electric current that flows in one direction only.<\/p>\n
AC is the type of current that is used in most homes and businesses. It is generated by rotating a coil of wire inside a magnetic field. The rotation of the coil causes the current to alternate between positive and negative.<\/p>\n
DC is the type of current that is used in batteries and some electronic devices. It is generated by a chemical reaction or by a solar cell.<\/p>\n
AC and DC are both important types of electricity. AC is used for power transmission and distribution, while DC is used for powering electronic devices.<\/p>\n
Option B is incorrect because AC and DC are not a rock band from Australia.<\/p>\n
Option C is incorrect because AC and DC are not average current and discharged capacitor.<\/p>\n
Option D is incorrect because AC and DC are not Atlantic City and District of Columbia.<\/p>\n","protected":false},"excerpt":{"rendered":"
