... Analysis of this transistor circuit to predict the dc voltages and currents requires use of Ohm’s law, Kirchhoff’s voltage law and the ß for the transistor. Determine the base BIAS current. Using Kirchhoff’s voltage law, subtract the 0.7VBE from VBB and the remaining voltage is dropped across RB. De ...
