A battery of `epsilon` and internal resistance `r` is used in a circuit with a variable external resistance `R`. Find the value of `R` for which the power consumed in `R` is maximum`.

A

`v_(0)`

B

`(v_(0))/(2)`

C

`(3v_(0))/(5)`

D

`(2v_(0))/(5)`

Text Solution

Verified by Experts

The correct Answer is:
(B)
by applying conservation of linear momentum `2mv_(0) = (2m + 2m)v rArr v = (v_(0))/(2)`
