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.

WebbA galvanometer is a sensitive device which can detect the presence of very small current in a circuit of the order of 100 mA. For measuring current of the order of an ampere, a low … WebbThe maximum value of the current that can be measured by the galvanometer is 𝐼 . Every point on the dial is thus a fraction of the current: half deflection means a current of 𝐼 2 , quarter deflection is 𝐼 4 , and so on.. We ideally want to add a certain amount of resistance to the galvanometer, such that the total resistances make the current 𝐼 . mike tyson quote on coming back
