load circuit. In this way many electrons pass into the load circuit before the
'hole'
combines with the electron. Thus a small current entering via the base can
produce a large load current and so a weak signal from a transducer can be used
to produce a strong signal to transmission or control purposes with the strength
of the signal controlling the number of, or modulating, the flow of electrons
from the emitter into the base.
It must be realized that a bias current to the base in addition to the actual
signal valu ...
