One other point is many professional type condenser or like type mikes
do have internal active amplification. They require a couple of
miliamps of operating current as opposed to just placing a charge on
the element. In this case it is normal for the mixing console to
provide "phantom power" which is sent along the mike line between the
console and mike. For those consoles that do not have internal phantom
power systems, a separate external source is required and provided.

Gus,
I think the term bias, or bias voltage is a pretty generic term when meaning applying a voltage or current to turn on a device, in this instance a microphone element that requires voltage to operate.
