 Question 141588: The current I in electrical conductor varies inversely as the resistance R of the conductor. Suppose I is 0.2 amperes when the resistance is 200 ohms. Find the current when the resistance is 250 ohms. Math Tutors I have no idea how to do this problem...thank you Found 2 solutions by scott8148, stanbon:Answer by scott8148(6628)   (Show Source): You can put this solution on YOUR website!"The current I in electrical conductor varies inversely as the resistance R of the conductor" __ I*R=k __ k is the constant of proportionality .2*200=k __ 40=k I*250=40 __ I=.16 Answer by stanbon(60778)   (Show Source): You can put this solution on YOUR website!The current I in electrical conductor varies inversely as the resistance R of the conductor. Suppose I is 0.2 amperes when the resistance is 200 ohms. Find the current when the resistance is 250 ohms. -------------------- I = k/R Find k: 0.2 = k/200 k = 40 ----------- EQUATION: I = 40/R --------------- If R is 250 ohms, find I. I = 40/250 I = 0.16 amps ================== Cheers, Stan H.
