The emitter diode of the transistor is forward biased by applying the required positive base bias voltage via the current limiting resistor RB. Assuming a standard bipolar transistor, the forward base-emitter voltage drop will be 0.7V. Then the value of RB is simply: (VCC â VBE)/IB where IB is defined as IC/Î².
