NEET 2018 Physics Resistors MCQ Question
Type: MCQ-conceptual-Medium-Class 12
A set of 'n' equal resistors, of value 'R' each, are connected in series to a battery of emf 'E' and internal resistance 'R'. The current drawn is I. Now, the 'n' resistors are connected in parallel to the same battery. Then the current drawn from the battery becomes 10 I. The value of 'n' is
A
10
B
11
C
20
D
9
Correct Answer
Option A
Detailed Explanation
Using the formula for resistors in series and parallel, we equate the new current to 10 times the original current to solve for 'n'.
