Flash light toy circuit made of transistor oscillator
Source: InternetPublisher:三岁就很酷 Keywords: flash lamp transistor oscillator resistor Updated: 2020/06/10
Shown is a flash toy circuit composed of a transistor regulator . Rl and R2 are connected in series to form a voltage divider circuit to provide bias (or base current) for the base (B) of transistor
VT1. VT] and VT2 form an oscillator. , thus driving the light-emitting diode to shine. R3 is the load resistor
of vri collector (c) , and the center is the resistor of VT1 emitter (E). Rs is the emitter (E) load resistor of VT2 .
