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 Missed Miscarriage. A missed miscarriage is often known as a silent miscarriage because women generally do not have common miscarriage symptoms, such as vaginal bleeding, heavy cramping, or expulsion of fetal tissue. With a missed miscarriage, the placenta may still release hormones, which can continue the signs of pregnancy for women.
