What is the maximum resistance which can be made using five resistors each of 1/5 Ω?

  1. 1/5 Ω
  2. 10 Ω
  3. 5 Ω
  4. 1 Ω

Answer

The maximum resistance is obtained when resistors are connected in series combination. Thus, equivalent resistance obtained by connecting five resistors of resistance 1/5 Ω each, in series = (1/5 + 1/5 + 1/5 + 1/5) = 1 Ω

The correct option is D.
