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.
Some women do not experience any symptoms of miscarriage at all; however, possible signs besides bleeding include: 1  Mild to severe cramps. 2  Back pain. 3  Loss of pregnancy symptoms, such as nausea or vomiting. 4  White-pink mucus.5  Passing tissue or clot-like material.ome women do not experience any symptoms of miscarriage at all; however, possible signs besides bleeding include: 1  Mild to severe cramps. 2  Back pain. 3  Loss of pregnancy symptoms, such as nausea or vomiting. 4  White-pink mucus. 5  Passing tissue or clot-like material.
