Question 199Electricity & Electronics - 1st Asst/Chief

The correct answer is D) from the bottom of fuse "1" and the top of either fuse "2" or fuse "3". The reasoning behind this is that to definitively determine if a fuse is blown, you need to measure the voltage drop across that fuse. By connecting the voltmeter leads from the bottom of fuse "1" to the top of either fuse "2" or "3", you can directly measure the voltage across fuse "1" and determine if it is blown based on the voltage reading. The other options are incorrect because they do not allow you to directly measure the voltage across the specific fuse in question (fuse "1"). Measuring between the tops or bottoms of different fuses would not provide the necessary information to determine the status of fuse "1".
