TOUCH SENSITIVE OSCILLATOR

basic electronics ,The oscillator works when the ends of the wire (c & d) are pressed by your fingers. The tone changes as the two points are pressed harder. Try the experiment with wet hands. Your body acts as a resistor and completes the circuit thus producing the sound. When you press the two ends of wires, the body resistance decreases and therefore the frequency also changes.

LOW FREQUENCYY OSCILATOR LOW FREQUENCYY OSCILATOR Wire the Cireuit as shown in the diagram. Since this is your first Circuit, make sure the connections are right. Check the wiring again and then connect the battery. A sound can be heard from the speaker. This is the low frequency audio oscillator. Compare the seund with the next Circuit(No.2, High Frequency Oscillator) and you can find the difference between the Low and High Fre- quency Audio Oscillators
