The BJT remains a device that excels in some applications, such as discrete circuit design, due to the very wide selection of BJT types available, and because of its high transconductance and output resistance compared to MOSFETs. The BJT is also the choice for demanding analog circuits, especially for very-high-frequencyapplications, such as radio-frequency circuits for wireless systems. Bipolar transistors can be combined with MOSFETs in an integrated circuit by using a BiCMOSprocess of wafer fabrication to create circuits that take advantage of the application strengths of both types of transistor.

What is h parameters transistor?
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 are the Disadvantages of h-parameters?
h parameters are temperatures dependent due to which there will be low resistance in the circuit, hence circuit will be less effective. Also it is used for small signals. help with more suggestions.
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.
Effective voltage and maximum instantaneous voltage relation?
For a sinusoidal waveorm, RMS (effective, heating) value = 2/pi x (peak voltage). It's not 2/pi for waveforms with other shapes. 2/pi = roughly 63.7%
What is the acceptable pi value in insulation resistance?
The PI value depends on the type of equipment being tested and the voltage level. Roughly it shall not be below the value of 2.0

balanced pi model for a long transmission line.
What is the rational approximation of pi?

What two atomic orbitals or hybrid atomic orbitals overlap to form the c equals c bond in ethene?
The p orbitals on each of the carbon atoms overlap to form the pi bond in ethene. This pi bond is created by the sideways overlap of two p orbitals.
What irrational number used in your daily life?
You will use the numbers pi and e (or applications which use them).
What does the mathematical constant pi stand for and what research has been conducted on its significance and applications?
The mathematical constant pi represents the ratio of a circle's circumference to its diameter. Research on pi has focused on its significance in geometry, trigonometry, and calculus, as well as its applications in various fields such as physics, engineering, and computer science. Scientists and mathematicians continue to explore the properties of pi and its role in understanding the natural world and developing new technologies.
What do you mean by a current controlled device?
It is modeled as a 2-port "black box", where the input terminals accept a current (and are modeled by 'zero' resistance to that current), and the output is a function of the input current. the output may be a voltage or current (or other varying physical parameter, such as resistance). A bipolar transistor is well modeled as a current controlled device. The collector (output) current is a function of the base current: Ic = Beta * Ib. The hybrid-pi model changes that from a current controlled device to a voltage controlled device: Ic = F(Vbe), but the BJT transistor is still basically a current controlled device.
What calculation use the pi number?
There are very many calculations which use pi. Many of them are in geometry: areas of circles and ellipses, volumes of solids of revolution. But there are also many applications in statistics.
