Thank you tooki. Please excuse the newb errors
The figure I quoted was the figure the multimeter read in diode mode. After much searching previously online, the only references i found to what the meter reads in diode mode was being refered as voltage drop.
No worries, ALL of us were newbies at some point, and this is the beginners forum. (Which is why I also gave some feedback on terminology. Thanks for being receptive to it!)
Yes, the diode drop is indeed a true voltage drop, meaning its unit is volts. Assuming you didn’t overlook a decimal point (in which case it’d be e.g. 0.45V), then that’s in whole millivolts (mV).
So were you simply using diode mode as a continuity tester? In that case, the values don’t tell you too much, if you don’t already understand what you’re looking at.
Here’s a good video on the basics of caps:
