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.
Symptoms of a miscarriage include: 1  Bleeding that progresses from light to heavy. 2  Cramps. 3  Abdominal pain. 4  Fever. Weakness. 5  Vomiting. Back  pain.
There is a lot of variation in the symptoms of a miscarriage. If you suspect that you miscarried, you should definitely see your doctor. Sometimes, women have partial miscarriages and need a D & C. I bled slightly for 2 days when I had a miscarriage and then started to hemorrage.
