Current remains same while in our case resistance is doubles.
|Hariom said: (Nov 8, 2013)|
|Here R constant but current is variable so current double.|

Multiply 2 both side.
2V = 2IR.
Voltage and current varies not resistance.
|Tapasree Ghosh said: (Jul 8, 2015)|
|V = IR.
Now 2*v = 2*I*R.
We know that when resistance is high then small amount of current can pass but when resistance is low then high amount of current can pass.
So here as the current will be multiplied by 2 not R. Thus, option D is correct.

|Golsh, exactly true.|
