Identify the element which makes the following scenario INCORRECT 11. An electrician is testing a switch using a multimeter as an ohmmeter. The the is not installed. First, the electrician connects the two leads of the meter to two terminals of the switch where the power conductors would be con nected it the switch were installed. The switch is in the OFF position, and the meter shows maximum resistance. Then, the electrician opens the switch to the ON position, and the meter shows a reading very close to zero. The electrician What is wrong with this scenario? a. When a switch is in the OFF position, the ohmmeter should show zero resistance b. An ohmmeter cannot be used to test an isolated electrical device c. When the switch is fipped to the ON position, it is closed, not opened d. In order to test resistance, a multimeter needs to be set as an ammeter. 12. "Meggers" are used to measure very high voltages very high resistance values very high currents none of the above a. b. c. d. When removing the outer sheathing from a length of cable in order to strip the individual conductors, you should often start your cut about the end of the cable. 13. r cut from 2 to 4 inches 6 inches a. b. 8 to 10 inches at least 1 foot c. d. Which conductor size is most appropriate for typical lighting and wall outlet circuits in residential settings? 14. a. 8-gauge b. 10-gauge c. 12-gauge d. 14-gauge 18
