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.
1 Miscarriage (either threatened or imminent), which is the spontaneous loss of a pregnancy in the first 20 weeks. 2  Often, the bleeding or spotting that occurs during a miscarriage will be accompanied by other symptoms, such as cramping or abdominal pain.
