Let R1 be the resistance equivalent to a connection of three equal resistors of value x di
one of which is connected in series with the other two connected in parallel; let R2 be the resistance
equivalent to a connection of three equal resistances of value y of which one is connected
in parallel with the other two connected in series.
What relationship must exist between x and y so that R1 = R2?
A) x = 4y/9
B) y = 4x/9
C) y = x
D) y = 3x/2
E) x = 3y/2
