R2 and R3 are greater than R1 means their resistance is more

Hey mate here is your answer


If r1 is in series with parallel connected to r2 and r3, the total current decreases if r2 opens.

Explanation:

Before opening of r2
Req1=r1+r2r3r2+r3
Req1=r1+r31+r3r2 (1)
After opening of r2:
hence r2=infinity (2)
write down (1) after substitution of (2)
Req2=r1+r3[sincer3r2=0 if r2=infinity]
Req2=r1+r3 (3)
from  (1)&(3)
Req2>Re
