Resistors placed in series create a total resistance that is found by simply adding the values of the resistors. (Knowing the applied voltage isn't necessary to solve this problem.) Rt = R1 + R2 + R3 = 2 ohms + 4 ohms + 6 ohms = 12 ohms

It depends on the resistance of the three resistors. Total resistance in a series circuit is the sum of the individual resistances.

A parallel circuit is a circuit in which the resistors are arranged with their heads connected together and their tails connected together. in parallel combination voltage remains constant and current varies . The total resistance of a set of resistors in parallel is found by adding up the reciprocals of the resistance values..

If three 15-ohm resistors are connected in parallel, then their net effective resistance is 5 ohms. It makes no difference what they're connected to, or if they're connected to anything, or whether or not you have any plans to ever connect them to anything.
