When resistors are connected in parallel, the supply current is equal to the sum of the currents through each resistor. The currents in the branches of a parallel circuit add up to the supply current.

1 R = 11 36 R = 36 11 R = 3.27 Ω This means that the three individual resistors can be replaced by one resistor of 3.27 Ω. Adding resistors in parallel decreases the total resistance.
