Do twisted power cables use more energy?

    I don’t believe they do.  Twisted pair cables – consisting of two insulated wires twisted together – commonly used by older telephones, helps reduced electromagnetic induction.

    From my memory of electricity and circuits in physics class in college the length of the cable would not change the energy required to get through the cable.  Since cables are made of good conductors with minimal resistance the voltage required would have more to do with the capacitors and resistors in the circuit.
