I'm trying to measure the current of a UV led @ 3.3v, 10ohm(smallest I have) shunt resistor.
It's my first time measuring current, and I'm confused about the readings at different ranges on my multimeter.
ah so I need to measure voltage across the resistor and use ohm's law got it.
on another note, when I insert the multimeter directly in series with the circuit, it seems to read over limits at 200mA range.
Is there something obvious I'm doing wrong here as well?
