Solution
1. By Ohm's law we have, V=IR  or R=V/I
As the resistance increases, the current decreases, provided all other factors are kept constant.


2. Using Ohm's Law,
I = V/R
I' =2VR/2I' = 4I

Hence the current becomes 4 times.

3. Ohm's law.

Ohm's law states that the potential difference across the ends of the conductor is directly proportional to the electric current flowing in the conductor. V directly proportional to I ( current).
