Answer:

#"The equivalent resistance is 1"Omega#

Explanation:

#"Since P,Q and R resistances are parallel,their equivalent is : "#
#1/M=1/2+1/3+1/6#

#1/M=(3+2+1)/6#

#1/M=6/6#

#1/M=1#

#M=1Omega#

#M("equivalent resistance of P,Q,R")#

#"Since The circuit current does not pass ,the resistance S does not affect the equivalent resistance."#

#"The equivalent resistance is 1"Omega#
