Question

The potential difference across an electrical component of fix resistance decreases to half it former value.What change will occur in the current passing through it?

Answer 1

the current will become half as well

Answer 2

♤ We know that

I = V/R

If V' = V/2

I' = V'/R

= V/2R

= 1/2

Therefore , the current will also become half of its previous value.
