Designing Sexy Signal Flow
Where do the electrons go?

With this you should understand completely; the reason a device
must receive a positive and negative wire in order to complete its
electric current. It is required so that the tiny electrons have
someplace to go. All circuits must be completed with a positive and
negative wire. One contact at the end of a cable allows the atoms in
the positively charged wire to shed its electrons, while another
contact allows the negatively charged wire to collect electrons.
Basically, when electricity flows into circuitry, it throws the copper
atoms off balance. The electrons stay in motion, in a constant effort
to balance the element. A positively charged copper atom ‘pulls’
electrons from its neighbor to get back to neutral. It is important that
you understand the relationship between electricity and your signal.

What is signal?

Signal refers to interruptions in the already established electric
current. This is where you must shed the linear thinking. Try not to
imagine electricity traveling down a wire, as this is inaccurate. When
your equipment is turned on, all of the wires and all of the circuits
incorporated in your signal path become charged with electricity. All
of the circuitry and wires form a giant loop of copper that contains
consistently flowing electrons. Your microphone is almost like a mini
generator. The energy that fuels it: compression waves. When the
capsule contained within your microphone vibrates it interrupts or
taints the flow of electricity. This creates a signal.
