Simple Diagram Of Transistor. The collector which is the positive lead. A very simple low power three stage transistor amplifier circuit is shown below.
It indicates the working of the transistors through two different leds. A transistor is similar to a relay in the sense that you can use it to turn something on and off. Many simple transistor configurations like rain alarm delay timer set reset latch crystal tester light sensitive switch and many more have been discussed in this article.
Collector to base biasing is employed for each stages and it is enough for circuits like this.
The transistor is like an electronic switch. A simple way you can think of it is to look at the transistor as a relay without any moving parts. It is just enough to make led b glow dimly. Simple transistor circuits for new hobbyists.
