Description

This apparatus provides a self-contained unit to
enable students to study the charge and discharge
characteristics of a capacitor.
The large value of C (0.01F) and the resistor chosen
give a time constant of about 50 seconds so that
students can easily take a manual set of readings
for plotting a graph. Data-logging equipment can
just as easily be used and if a faster response is
required a parallel resistor could be plugged in.
Connections are by standard 4mm plugs and
analogue or digital meters are suitable.
