Answer:

Least equivalent resistance obtained on combing three resistors 2 Ω , 3 Ω and 6 Ω is 1 Ω

Explanation:

A number of resistors give the minimum Equivalent resistance when they are connected in Parallel combination.

We are given with three resistors of resistances 2 Ω , 3 Ω , 6 Ω

Using the Law of combination of resistors in parallel combination , that is stated as :

Reciprocal of the combined resistances of a number of resistances connected in parallel is equal to the sum of the reciprocals of all the individual resistances .

1/R = 1/R₁  + 1/R₂  + 1/R₃  +  .....

●Calculating the equivalent resistance of circuit when 2 Ω , 3 Ω and 6 Ω resistors are connected in Parallel to get least resistance.

Let, their equivalent resistance be R

→ 1/R = 1/2  +  1/3  +  1/6

→ 1/R = ( 3 + 2 + 1 ) / 6

→  1/R = 6 / 6

→ 1 / R = 1

R = 1 Ω

Therefore,

The least resistance we can make out from combining three resistors as 2Ω , 3Ω and 6Ω is 1 ohm .
