Answer 1

$\huge \fbox \red{❥Answer}$

✒ According to the ohm's law, V = IR (but I is not given)

I= VR

If potential difference decreases by half to its former value, then V' = V /2 Therefore, as the resistance remains constant.

New current will be created.

I' = V'/R

= (1/2)/R

by half

1 = 1/2

(1/2) (V/R) - P. Difference Decreased

(1/2)
