For You To Do
- The stripe colors on the 100 K resistor are brown - black - yellow, and those on the 10 K resistor are brown - black - orange. Here are capacitor markings:
0.001 μf : 102
0.01 μf : 103
0.220 μf : 224
- a) The pin at the bottom left is pin 1; from there, pin numbers increase counterclockwise.
- Be sure wires are pushed completely into sockets (about 3 mm).

- a) A tone sounds.
- a - b) the larger the capacitor, the lower the tone.
c) Switching the two resistors produces a lower tone.
d) Switching the two resistors changes the quality of the sound.
- a) To make the sound as low as possible, use the largest capacitor and the resistors switched as in Step 15.
b) When you touch the speaker, you feel vibration.
