Usage/History: Rheostats are used to adjust the voltage
and current flow through electrical circuits. Thus, for example,
if a voltage source is connected across the two terminals of
the resistance coil, the central slider can be adjusted to give
any voltage between the extremes. The heavy wire in this example
enables it to carry a fairly high current.
Description: The rheostat is as described in the catalog
description The instrument is stamped "6 OHM" and "7.3
AMP" on the top of the bakelite slider knob, corresponding
to item A in the catalog description. The left rear leg is broken
off.
