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.
The main sign of miscarriage is vaginal spotting or bleeding, which can vary a from slight brownish discharge to very heavy bleeding. Other symptoms include: 1  Cramping and pain in the abdomen. 2  Fluid discharge from the vagina. 3  Tissue discharge from the vagina. 4  Feeling faint or light-headed.
