In order to know why voltage is kept constant for input characteristics and current is kept constant for output characteristics in CE mode, first we have to know the hybrid parameters and its model.
The hybrid parameters are generally used to determine amplifier characteristic parameters such as voltage gain, input and output resistance etc. We have already know that amplifier characteristic parameters may be determined by using current gain and values of other circuit components. Hybrid methods had the following advantages:
Value of circuit components are easily available and
The procedure followed is quite simple and easy to understand.
