if the resistance of an electrical component remains constant while the potential difference across to end of the component decrease half of its formal value what change will occur in the current through it

Answered by Manish1230

the current will also become half as potential difference is directly proportional to current.

anika27: can u explain a little bit

Manish1230: according to the Ohm's law potential difference is directly proportional to the current and indirectly proportional to the resistance. and if the resistance is the same in both the cases and only the current is changing so the resistance will not matter in our calculation so the only thing which will matter is the change in potential difference. in this case the potential difference is halved so the current will also be halved

let volt=v resistance=R current=I

V=IR (ohm's law)

I=V/R ......(1)

When V IS halfed

I=(V/2)/R

I=(V/2)*(1/R)

I=V/(2R)

I=(1/2)*(V/R)

SO CURRENT IS HALFED
