1. The problem statement, all variables and given/known data The minimum resistance obtained by connecting 50 resistances of 0.25 ohm each is A)50/4ohm B)4/50 ohm C)200 ohm D)1/200 ohm 2.Relevant equations 1.When resistances are connected in series, ▪R(equivalent)=summation of all individual resistances 2.When resistances are connected in parallel , ▪1/(equivalent resistance) =1/(summation of reciprocals of individual resistances) 3. The attempt at a solution Minimum resistance is usually obtained when all resistances are connected in parallel (better than adding them all up). So,it should be coming as 4/50 ohms,using formula 2,but the answer is given as D,1/200 ohms. How do you arrange these resistors to have an equivalent resistance of 1/200 ohms??
