Notes on the Circuits Experiment Board
The springs are securely soldered to the board and serve
as a convenient method for connecting wires, resistors
and other components. Some of the springs are con-
nected electrically to devices like the potentiometer and
the D-cells. In the large Experimental Area, the springs are
connected in pairs, oriented perpendicular to each other. This
facilitates the connection of various types of circuits.

If a spring is too loose, press the coils together firmly to
tighten it up. The coils of the spring should not be too
tight, as this will lead to bending and/or breaking of the
component leads when they are inserted or removed. If a
spring gets pushed over, light pressure will get it straight-
ened back up.

The components, primarily resistors, and small wires can
be stored in the plastic bag supplied in the storage case.
Encourage students to keep careful track of the compo-
nents and return them to the bag each day following the
lab period.

When connecting a circuit to a D-cell, note the polarity
(+ or -) which is printed on the board. In some cases the
polarity is not important, but in some it will be impera-
tive. Polarity is very important for most meters.

Connections are made on the Circuits Experiment Board
by pushing a stripped wire or a lead to a component into a
spring. For maximum effect, the stripped part of the wire
should extend so that it passes completely across the spring,
making contact with the spring at four points. This produces
the most secure electrical and mechanical connection.

The Experiments
The experiments written up in this manual are develop-
mental, starting from an introduction to the Circuits
Experiment Board and complete circuits, through series
and parallel circuits, ultimately resulting in diode and
transistor characteristics. These experiments can be used
in combination with existing labs that the teacher em-
ploys, or may be used as a complete lab unit.
