Is Student I correct? Why ar why no ii. Is Student 2 correct? Why or why not?

Explanation / Answer

when the wire in the circuit is cut

the circuit breaks and there will be no current flowing through the circuit

but there will be potential difference between the two terminal where the wire is cut

the circuit becomes open when the wire is cut (i = 0)

in closed circuit we have current but no potential difference
