The relation between R and r (internal resistance of the battery) for which the power consumed in the external part of the circuit is maximum.

A

R = r

B

`R = r//2`

C

`R = 2r`

D

`R - 1.5r `

Text Solution

Verified by Experts

The correct Answer is:
B
b. Circuit is forming a Wheatstone bridge, so `R = 2R`. For the maximum power transfer, 2R = r.
