6. A multimeter can be used to measure resistance while the circuit is powered on; the answer given by LZ is correct. . . But I remember this doesn’t work, right?

It is not possible to take measurements while the device is powered on; this resulted in an incorrect answer. I’m sorry! The reason why one should not measure resistance with a multimeter while it is under voltage is, first, that it affects the accuracy of the measurement results, and second, it may damage the multimeter.
