Answer :

The minimum resistance to the flow of electrical current is achieved when
the resistors are connected in parallel, just as the minimum resistance to the
flow of vehicular traffic is achieved when several lanes are built in parallel.

When 5 equal resistors are connected in parallel, the net resistance of their
combination is just 1/5 of the value of each one. 

So 5 equal resistors in parallel, each with a resistance of 1/5 ohm, have a
combined net resistance 0f 1/25 ohm.
