A) \[R<r\]
B) \[R>r\]
C) \[R=r\]
D) Any other value of R
Correct Answer: D
Solution :
For current in the external circuit to be maximum, total resistance \[(r+R)\] should be minimum. \[r\]is a constant for a cell, so R should be zero. This value of \[R\] is not mentioned explicitly in any of the given options. Therefore, the correct option must be [d].You need to login to perform this action.
