Phot transistor
WebJun 21, 2012 · 7. First move the LED to the transistor's collector, and add a series resistor. You now have a common collector circuit, and the 2N3904's base is at 2.7 V or higher, depending on the LED voltage. Then if there's no current through the phototransistor you have 300 μ A base current (0.3 V / 1 kΩ).
