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.
Other symptoms of a miscarriage include: 1  cramping and pain in your lower abdomen. 2  a discharge of fluid from your vagina. 3  a discharge of tissue from your vagina.  no longer experiencing the symptoms of pregnancy, such as feeling sick and breast tenderness.
