Transient states in electrical circuits with a nanowire.
We have observed conductance quantization of macroscopic metallic contacts in a circuit with a mechanical relay and LC circuit. The investigation has been performed outdoors at room temperature, and it was focused on measuring the conductance between two vibrating metal wires. Transient states of the current in a circuit are also described in the paper, this description includes a contact with quantized conductance. We can assume the occurance of oscillations in an electrical circuit with a relay, due to existence of conductance quantization at relay contacts. When designing a circuit with transmitter, one should take into account the fact that the resistance of its contacts together with the capacity and inductance of the whole system may lead to the appearance of oscillations.
