To find the resistance of galvanometer

Webb11 okt. 2016 · edit: I was very sleep deprived and my mind blanked out on the answer. Just find the voltage of the known resistor w/ the ohmemeter, and use ohm's law (i=v/r) to get the current, then use the current with the unknown r's voltage & ohm's law to get the resistance. Sorry to waste everyone's time. I have an unknown resistor and a 1k resistor.
