Question

Keeping the potential difference constant, the resistance of a circuit is halved. Then, how much does the current changes?

Answer 1

Answer:

It will get double.

Explanation:

We all know that ,

$v = i \times r$

$i = \frac{v}{r}$

We can see that current is inversely proportional to resistance.

So , if we decreases the resistance , current will increase.
