Since the 2N3904 is an NPN transistor, that means the base needs positive biasing (appropriate voltage levels and resistance) to turn on the collector emitter junction for proper current flow. Use of a load resistor (R1 above) is also important so there is not too much current being driven through the LED and transistor. 2N3705 Bipolar Transistors Page 3 09/05/08 V1.1 Specifications VCEO (V) VCBO Maximum (V) IC (mA) hFE Minimum at IC = 50mA fT Minimum (MHz) Ptot (mW) Pakage Part Number 30 50 0.8 50 100 625 TO-92 2N3705 2N3904 fT 250 300 − − MHz Output Capacitance (VCB = 5.0 Vdc, IE = 0, f = 1.0 MHz) Cobo − 4.0 pF Input Capacitance (VEB = 0.5 Vdc, IC = 0, f = 1.0 MHz) Cibo − 8.0 pF Input Impedance (IC = 1.0 mAdc, VCE = 10 Vdc, f = 1.0 kHz) 2N3903 2N3904 hie 1.0 1.0 8.0 10 k Voltage Feedback Ratio (IC = 1.0 mAdc, VCE = 10 Vdc, f = 1.0 kHz) 2N3903 2N3904 hre 0.1 0.5 5.0 8.0 X 10−4 Jan 02, 2020 · One of the various parameters of the 2N3904 transistor is known as the beta, or current gain, which is the ratio of the collector current to the base current.

The current gain depends on the collector current, but figure on 50. With a base current of 20mA, that's a collector current of way more than the 2N3904 can handle, so 20mA will saturate it thoroughly. You can probably get by with a lower base current.
