हिन्दी10 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 :
View Answer & Solution
Correct answer · Option B
\( 100 \)
Explanation
Series resistance \( R_s = 10R \), Parallel resistance \( R_p = \frac{R}{10} \). Current in series \( I_s = \frac{E}{10R} \), current in parallel \( I_p = \frac{E}{R/10} = \frac{10E}{R} \). Ratio \( I_p / I_s = 100 \), so \( n = 100 \).
