Question

answer fastttttttttttttttttttttttt​

Answer 1

Hey mate..

We know that.

V =I × R

I=V / R

From the data..
R=R
V= V/2

So..

I=R/V/2
=2R/V
I/2= R/V

So current is also half

Answer 2

We know that potential differences is directly proportional to current.

So when we increase the pd the current increases.

When the pd is decreased to half current also reduces to half

Hope it helps
