Hybrid Parameters are the values which is used to find FREQUENCY RESPONSE of a low frequency transistors.
you may have doubt like why we are using only H-PARAMETERS why not HYBRID-PI models because...,
h-parameters values are constant at low frequency
moreover, at low frequency transition model we have assumed that the response of transistor to changes of input current or input voltage is instantaneous this is the reason why we had neglected shunt capacitances . as there were no shunt capacitances there is no chance of using hybrid-pi model.
i hope you got answer for your question
What else can I help you with?
Which is the smallest of the four h-parameters of transistor?
hf
Why you use h parameter?
Type your answer here... TO DECREASE THE COMPLEXITY . ANSWER: h parameters are used to analyze small signal behavior o a transistor.
What is the importance of H-parameter of transistor amplifier?
In transistors, current gain plays a significant role. In h parameters, one of the parameters is hfe which is current gain. It is easier if the parameters chosen represent some significant properties of the device. Some other parameters of importance in transistors are input resistance hie and output resistance 1/hoe.So it makes sense to analyse transistors with h parameters.

How are h parameters of a transistor measured in laboratory?
In the laboratory, h-parameters (hybrid parameters) of a transistor are measured using a small signal AC test setup. The transistor is biased in its active region, and small AC signals are superimposed on the bias. The input voltage and output current are measured, allowing the calculation of h-parameters such as input impedance (h11), forward current gain (h21), output admittance (h22), and reverse voltage gain (h12) using the appropriate equations. Typically, these parameters are determined through a combination of voltage and current measurements taken at the transistor's terminals.

Why h parameter are not used for transistor mode at high frequency?
finding h parameters involves open and short circuits which is difficult to obtain at high frequencies due to stray inductance and capacitance

r parameter is resistance parameter
What are the advantages of hybrid parameters of transistors?
Oh, honey, buckle up! Hybrid parameters of transistors, like hfe and hie, can give you a better understanding of how a transistor behaves in a circuit. They can help you design circuits with more precision and predict how changes will affect performance. So, if you want to avoid blowing up your circuits, paying attention to these parameters is key.
Why CE transistor is more temperature senstive than CB transistor?
In CE transistor volteage divider biasing is used, which is independent of temperature and other parameters.
