Project #506
OBJECTIVE: View charging and discharging a capacitor.
Using the meter (M2), we can monitor the charging and discharging of a
capacitor. First turn off the switch (S1).
Charging:
Connect the meter (M2) to points A & B (positive pole
downward). Turn on the switch (S1). The 100
μ
F capacitor (C4) charges
and the meter deflects, slowly returning to zero.
Discharging:
Connect the meter to points B & C (positive pole
downward). Press the switch (S2). The capacitor discharges and the
meter deflects, slowly returning to zero.

Project #507
OBJECTIVE: Using the meter with the space war IC.
Set the meter (M2) to the LOW (or 10mA) setting. This is another circuit
using the meter to monitor the output of an IC.
Turn on the switch (S1). Press switch (S2) to start the circuit. As the
space war IC (U3) outputs a signal, the meter will deflect. When the
circuit stops, start it again by pressing switch (S2).
