Question

We have four resistance of 1 ohm . 2 ohm, 3 ohm and 4 ohm how they should be connected so we can obtain a combination such that its equivalent resistance is less than the minimum value present in the combination...

Answer 1

You should connect the resistances in a parallel circuit.
Equivalent resistance= 1/R1+1/R2+1/R3+1/R4
Therefore it will be less than the minimum value present in the combination.

Answer 2

You should connect the resistances in a parallel circuit.
Equivalent resistance= 1/R1+1/R2+1/R3+1/R4
Therefore it will be less than the minimum value present in the combination.
