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 are several common signs of miscarriage. 1  Bleeding becomes heavy. 2  Pain is like bad period pain or birth contractions. 3  Faintness and nausea. 4  You pass pieces of placenta which look like blood clots or pieces of raw liver.5  You may see the fetus. 6  If you are more than 4 months pregnant, the fetus may be alive.here are several common signs of miscarriage. 1  Bleeding becomes heavy. 2  Pain is like bad period pain or birth contractions. 3  Faintness and nausea. 4  You pass pieces of placenta which look like blood clots or pieces of raw liver.
