Using a transistor ... control circuits. We’ve embedded his twenty-minute video after the break. In it he talks about the use of transistors, the difference between NPN and PNP transistors ...

Each of the seven outputs works like this simplified diagram. Inside the ULN2003 ... Each of the Darlington pairs (which act as single NPN transistors) is configured as open collector, and the ...

Circuit diagrams often show transistors in switching circuits. For an ideal NPN transistor, the switch-on voltage at the base is typically 0.6V (acceptable range is 0.6V to 0.8V). This means that ...

The transistor ... diagram of a transistor switching circuit, you should be able to say what the circuit is used for and be able to explain how it operates. This transistor switching circuit uses ...
