Answer:
Correct option is
C
double
Answer is C.
According to Ohm's law, V = IR. That is, I = V/R.
Now, if the resistance is halved and the voltage remains the same, the new value of current becomes, I
′
=
2
R
V
=
R
2V
.Thatis,I
′
=2(
R
V
)=2I.
Hence, the current will become double.

Answer:
d) does not depend
Explanation:
resistance of a conductor not depend of potential difference across conductor.
don't use the formula V=IR
