heres a OHMmeter question 8)

[Ropy]

I picked A.

Lawd, mi lef Physics 20 year ago! How mi fi member how it go now? Mus be parallel. Picked B. ???

[makaveli]

sorry guys nobody got it right but the good thing is u learn something new

Answer: D - open the circuit that contains the device being tested

Explanation: To be perfectly honest, I want to get a good meter question in so I took this one directly from a solid source and a good quiz site. I received a PM saying that there could be 2 possible answers but I don't think that is accurate given the following explanation stright from the source. But, please, let me know if this is inaccurate.

there are multiple ways of testing but taking out of the circuit is the best test for a device which is passive, like resistor, capacitor and inductor. you could also use that method for basic active devices like transistors and diodes.

so you would put in series to test for current or resistance.
in parallel for voltage.
both of those tests involve using a power supply being on.

take out off circuit when the device is a chief suspect.

however, when it comes to fault finding, if you have the range of voltages that the circuit should have, then you can meter them out to see where the voltages are falling off.

high speed circuits are def out with that kind of testing and you would employ oscilloscopes or logic testers for those.

dat nuh fair star mi did choose D then seh cho a A star.... >
