Transistor Inverter Circuit Diagram. When the switch is open or off the led is on. When the switch is closed a small current flows into the base b of the transistor.
You do not. When the switch is open or off the led is on. It is hard to find equipment.
It is just enough to make led b glow dimly.
The small base current controls the larger collector current. When the input is logical 1 the output is logical 0. When the switch is closed a small current flows into the base b of the transistor. Also 500w inverter circuit for you.
