If resistors are in parallel and one is open the total resistance.

Will increase hence current will decrease.

If R2 is open then R1 & R3 will be in series so current should remain same.

This depends on which type of source we are using, current or voltage source.

@Summo.

We are comparing current before and after the open R2, so current decrease.

Total I = i1+(i2+i3)....

If r2 is open then no current in that node and so total I= (i1+0+i3)...
So, overall current in circuit decreases.
Correct me if I am wrong.

Current remain the same becuase R1 and R3 forms the same.

If R2 opens, then total resistance will increase and hence, current will decrease.
