Three identical resistors are connected between terminals P and Q in different networks X, Y and Z as shown. [Figure showing three resistor networks: X (two parallel resistors in series with one), Y (three resistors in series), Z (two series resistors in parallel with one)] What is the order of increasing combined resistance between P and Q (lowest first)?
