**Solution :**

1.When the resistance of the conductor increases then the current will decrease (option B).

1.

We know that, according to Ohm's law :

I = V/R

i.e. I ∝ 1/R

where, I = current

V = potential difference

R = resistance

The current is inversely proportional to the resistance. Hence, when resistance increases the current decreases

**2.**We know that,

I = V/R

when potential difference is doubled and resistance is halved then,

I = 2V/(R/2)

I = 4 V/R

Hence, current becomes the four times (option D).

**3.**Straight line is obtained on drawing the graph of current against potential difference, this proves Ohm's law (option B).

Kindly post the different questions in different thread.
