NEET · Physics · STD 12 - 3. current electricity
\(10\) resistors, each of resistance \(R\) are connected in series to a battery of \(emf\) \(E\) and negligible internal resistance. Then those are connected in parallel to the same battery, the current is increased \(n\) times. The value of \(n\) is :
- A \(1000\)
- B \(10\)
- C \(100\)
- D \(1\)
Answer & Solution
Correct Answer
(C) \(100\)
Step-by-step Solution
Detailed explanation
\(I_S=\frac{E}{10 R}\) \(I_P=\frac{E}{R / 10}=\frac{10 E}{R}\)
