R < r1, smaller than the smallest.

Q. Two resistances $r_{1}$ and $r_{2} (r_{1} < r_{2})$ are joined in parallel. The equivalent resistance R is such that

$R < r_{1}$

$r_{1} < R < r_{2}$

$r_{2} < R < r_{1} + r_{2}$

$R > r_{1} + r_{2}$

$R < r_{1}$ , smaller than the smallest.

Q. Two resistances r1​ and r2​(r1​<r2​) are joined in parallel. The equivalent resistance R is such that

R<r1​

r1​<R<r2​

r2​<R<r1​+r2​

R>r1​+r2​

R<r1​, smaller than the smallest.
