Circuit of bjt
WebBelow is a typical BJT receiving voltage divider bias: For the circuit above, we're going to assume that β=100 for the transistor. The base supply voltage, V BB, is calculated by: We calculate R B below, which we will use the next calculation for I E. Then, we calculate for the emitter current using the following formula:
