You decide to use the transistor bc548. This article focuses exclusively on biasing and if you have gaps in your knowledge then i recommend reading the earlier pages of this multi page article. Electronics Gurukulam Transistor Acts As A Switch Touch Switch Using Single Npn Transistor Npn Transistor Bc547 Bc548 Bc546 Pinouts Circuit Transistors are one of the most important circuit board components and replaced vacuum tubes in the mid 20th century allowing for the true miniaturization of electronics. Transistor bc548 switch . As discussed a transistor will act as an open switch during forward bias and as a closed switch during reverse bias this biasing can be achieved by supplying the required amount of current to the base pin. Transistor as a switch biasing. Bc548 transistor can be used in many general purpose applications. Bc548 as switch whe...
