Suppose you have three resistors of 20 Ω Ω , 50 Ω Ω and 100 Ω Ω . What minimum and maximum resistances can you obtain from these resistors?
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(12.5 Ω Ω , 170 Ω Ω )
Sol. For maximum resistance, all resistance are in series
R max = 20 + 50 + 100 = 170 Ω Ω
For minimum resistance, all resistance are in parallel
R min = 
= 12.5 Ω Ω
