Q. Explain Common emitter configuration?
Common emitter configuration: In this circuit the emitter is common to both input and the output.Such a configuration is also known as grounded emitter configuration. Here the input current and the output voltage are taken as the independent variables, whereas the input voltage and putput current are the dependent variables.
VBE = f1(VCE,IB)
IC = f2(VCE,IB)
