Homework Statement
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)
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??
