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.
Symptoms of early miscarriage. 1  Bleeding â light bleeding early in pregnancy is fairly common, and does not mean you will have a miscarriage.  Brown discharge: this may look like coffee grounds. This âdischargeâ is actually old blood that has been in the uterus for a while and is just coming out slowly.
