Led Transistor Schaltung. So you see how the transistor allows a circuit to be an led driver. When the inverter input is 12v the transistor in the first inverter will turn on and the led will come on and the inverter output voltage will be 0 2v.
The transistor amplifies this base current and the led spotlight bulb ends up receiving a current of 58ma at 11 13 volts 645 mw. The transistor used in this experiment was picked randomly from a box of salvaged components it was a bc238b npn type low power general purpose transistor. Schaltung 2 led schalter mit einem transistor eine led verhält sich anders wie eine glühbirne eine led leuchtet erst ab einer bestimmten spannung.
In this circuit diagram all leds blink as a moving in one direction.
Usually the signal from a microcontroller or logic gate does not possess sufficient drive current to power an led directly. When the inverter input is 12v the transistor in the first inverter will turn on and the led will come on and the inverter output voltage will be 0 2v.
