A battery of e.m.f. `10 V` 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

2.0 ohm

0.25 ohm

1.0 ohm

0.5 ohm

Text Solution

Verified by Experts

The correct Answer is:

For maximum power (internal resistance = Load resistance) i.e., r = `R = 0.5 Omega`
