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.
For most women, the bleeding is heavy with clots, but not severe-it is more like a heavy period. However, the bleeding can be severe in some cases. In some cases of miscarriage, there are no symptoms. The fetus stops developing or dies but it remains in the womb (uterus).
