You are given 10 resistors each of resistance 2Ω. First they are connected to obtain possible minimum resistance. Then they are connected to obtain possible maximum resistance. The ration of maximum and minimum resistance is ____.
(A) 100
(B) 10
(C) 2.5
(D) 25
Correct option (A) 100
Explanation:
Maximum resistance when connected in series.
RS = 20Ω
Minimum resistance when connected in parallel.
