This unit operates in conjunction with the TH-2204
Recording Timer in order to perform experiments dealing
with the behavior of electrical charges on a capacitor. The
Recording Timer functions as a switch, which alternately
applies a charging voltage across a capacitor, and then
discharges the resulting charge through a microammeter.
Changing rates and voltages can be varied and the effect
of resistance in various parts of the circuit may be
observed. This unit contains two capacitors of different
values and several resistors as well as material to modify
the Recording Timer for these experiments.
