Transistor Schematic. The transistor t1 and t2 constitute a basic voltage controlled lf oscillator with a loudspeaker working like a load. The base the collector and the emitter.
The oscillator frequency is formed by c1 r1 r4 and the external resistance between the measuring leads. Figure 1 shows an npn bjt schematic symbol a simple diagram of the structure and a diode model. The humble transistor q1 emitter e collector c base b transistor basics emitter to base junction is forward biased normally collector to base junction is reverse biased normally transistors are current operated devices so.
C2 behaves like a low frequency decoupling of this particular resistor.

The humble transistor q1 emitter e collector c base b transistor basics emitter to base junction is forward biased normally collector to base junction is reverse biased normally transistors are current operated devices so. The n p n structure is just representative. In small discrete quantities transistors can be used to create simple electronic switches digital logic and signal amplifying circuits in quantities of thousands millions and even billions transistors are interconnected and embedded into tiny chips to create computer memories microprocessors and other complex ics.
