A-LevelPhysicsD.C. circuitsOct/Nov 2019Paper 1 Q361 Mark
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)?
AX → Y → Z
BX → Z → Y
CY → X → Z
DY → Z → X
