The Triode

Comments Off

[Today’s run: Watson Road – 3.5 miles]

The cathode is the source.
The heater heats of course.
Electrons hurried by
added energy fly
and form a cloud of charge.

Voltage, potential, dearth
relative to the earth
inflicted on the plate
transmits a needy state:
electrons wanted here.

The getter tends the way,
keeps molecules at bay
so that electrons race,
but do not spark, through space,
like lightning in the sky.

The grid as a sluice gate
can change the flowing rate
while they cascade and fall,
respond to voltage call,
the current modulate.
