You are given one hundred 1 Ω resistors. What is the smallest and largest resistance you can make in the circuit using these?
The greatest possible resistance is the series combination of the resistors.
In series combination of hundred 1 ohm resistors equivalent resistance will be 100 ohm
The least possible resistance is the parallel combination of the resistors.
When resistances are connected in parallel then
1/R =100
R= 1/100 =0.01 ohm
