Question

what will happen to current passing through a registor, if the potential difference across it is doubled and the resistance is halved?*​

Answer 1

Answer:

Explanation:If the resistance of a circuit is halved and the potential difference is kept constant, then the current will become

Answer 2

Answer:

According to Ohm's law, V = IR. That is, I = V/R.

Now, if the resistance is halved and the voltage remains the same, the new value of current becomes, I′=2RV=R2V.Thatis,I′=2(RV)=2I.

Hence, the current will become double.
