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.
Signs of a Miscarriage. In early pregnancy, spotting is normal, but if you experience menstrual-like cramps or severe abdominal pain and bleeding, you may be experiencing a miscarriage and should call your health care provider.
