Question

Keeping the potential difference constant, the resistance of a circuit isade 4 times. By how much the current changes..... Guys plz tell this answer it's urgent i will mark u as brainliest..​

Answer 1

Answer:

As from Ohm's Law,

V = IR........1

Now, here V is constant.

Let , new resistance R' = 2R and assume that current flow be I'

So, from 1,

IR = I'.R',

-> IR = I'.2R,

Therefore, I' = I / 2

So the current is halved.
