Question

keeping the potential difference constant the resistance of a circuit is hafte by how much does the current change​

Answer 1

Answer:

According to Ohm's law, potential difference is proportional to electric current.

which means,

V= IR

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

if resistance is made half, then

V= I' x R/2

I'= V/R/2

I'= 2V/R

I'= 2(V/R)

putting (1)

I'= 2(I)

therefore, current become 2 times.

hope it helps..
