Solution
The correct option is
D
Any of these
Power dissipated by a device that carries current
I
when operated at a potential difference
V
is given by
P
=
V
I
$
If the device has a resistance
R
then we can use Ohm's law (
V
=
I
R
)
So
P
=
(
I
R
)
I
=
I
2
R
or
P
=
V
(
V
R
)
=
V
2
R
So all the options are correct. Option (D) is the answer.
