Abstract

The mechanism of amplificatfon of alternating current in the
investigated membranes system is based upon the properties of
membrane rectifiers, which represent the essential part of the
circuit. An important role in the effect of amplification of a.c.
is played by the intrinsic sluggishness' of the r ectifiers, which leads
to an excess of current already in the second half-period of the
first wave after the switching on of the impulse circuit. This excess
of current accumulates and amplification increases reaching finally
a constant value, which corresponds to a steady state of the system.
The current a mplification factor depends on the frequency
of the a.c. u sed in the m ain circuit: the lower the frequency of the
current applied, the higher the final value. This final value of the
current amplification factor is attained faster if the current
applied in the impulse circuit is higher.
