NEET 2023 Physics Resistors MCQ Question
Type: MCQ-numerical-Medium-Class 12
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
100
B
1
C
1000
D
10
Correct Answer
Option A
Detailed Explanation
In series, total resistance is 10R, and in parallel, it is R/10. The current increases by a factor of (10R)/(R/10) = 100.
