Suppose you have three resistors of 20ohm, 50 ohm and 100 ohm. What minimum and maximum resistances can you obtain from these resistors?

Q. Suppose you have three resistors of 20ohm , 50 ohm and 100 ohm . What minimum and maximum resistances can you obtain from these resistors?
(a) 15Ω , 170Ω
(b) 12.5Ω , 170Ω
(c) 12.5Ω , 150Ω
(d) 15Ω, 150Ω
Ans: A

For maximum Resistance , all the resistors are connected in series and for minimum resistance all the resistors are connected in parallel.
