Resistance and Power

Q1: What happens to current and resistance if the voltage doubles?

A Current doubles and resistance doubles.

B Current doubles and resistance is halved.

C Current remains the same and resistance doubles.

D Current doubles and resistance remains the same.

ANS:D - Current doubles and resistance remains the same.

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.
