We know that for obtaining maximum power, the internal resistance must be equal to variable resistance so, the value of R will 0.5 Ω .

Q. A battery of emf 10V and internal resistance 0.5 ohm is connected across a variable resistance R. The value of R for which the power delivered in it is maximum is given by :

0.5 ohm

1.0 ohm

2.0 ohm

0.25 ohm

We know that for obtaining maximum power, the internal resistance must be equal to variable resistance so, the value of R will $0.5 Ω$ .
