Project #409
OBJECTIVE: To build a circuit that checks the transistor.
Turn on the switch (S1), the meter (M2) does not move. Press the
switch (S2), the meter deflects and points to 10. This indicates the
transistor (Q2) is GOOD. The meter would only deflect a little or not
at all for a BAD transistor.

Project #410
OBJECTIVE: To make an adjustable current path.
This circuit is a simple voltage divider. When the variable resistor (RV)
is set to the far right, the voltage across the resistors (R4) and (RV)
are equal. Adjust resistor (RV) to the left, the meter (M2) deflects less,
as the voltage decreases.
