FORWARD BIAS - an external voltage that is applied to a PN junction to reduce
its barrier and therefore aid current flow through the junction. To accomplish
this function, the external voltage is connected so that it opposes the
electrostatic field of the junction.
REVERSE BIAS - an external voltage that is connected across a PN junction so
that its voltage aids the junction and thereby offers a high resistance to the
current flow through the junction.
