\(10\) resistors each of resistance \(10\,\Omega\) can be connected in such as to get maximum and minimum equivalent resistance. The ratio of maximum and minimum equivalent resistance will be \(..........\).
- A \(90\)
- B \(80\)
- C \(70\)
- D \(100\)
Answer & Solution
Correct Answer
(D) \(100\)
Step-by-step Solution
Detailed explanation
Maximum resistance occurs When all the resisters are connected in series combination \(\therefore R _{\max }=10\,R\) Here \(R =10\,ohm\) Minimum resistance occurs When all the resistance are connected in parallel combination \(R _{\min }=\frac{ R }{10}\)…
