What will happen to the current passing through the resistance, if the potential difference across it is doubled and the resistance is halved

let the current in first case be 'I', potential diff. 'V' and resistance 'R'
so... by Ohm's law I=V/R...
now in second case potential diff. is 2V and resistance is R/2 now applying ohm's law
I' =4V/R.....
substituting it we get,
I'=4I
it shows that new current is four times of old one
hope it helped...
if it did then plss mark it as brainliest
