y-parameters :-
I1=Y11V1 + Y12V2
I2=Y21V1 + Y22V2
so to obtain Y11 and Y21
make V2=0 , (shorting the output terminals)
Y11=I1/V1
Y21=I2/V1
so to obtain Y12 and Y22
make V1=0 , (shorting the input terminals)
Y12=I1/V2
Y22=I2/V2
as all the admittance parameters obtained are due to either shorting the input or shorting the output terminals so we ca;; these parameters as short circuit admittance parameters
In the Z-parameter Equations the independent parameters are Currents i.e., i/p And O/p . therefore to find any of the parameter(Z11,Z12,Z21,Z22) We have to either open circuit the input or the output port .as we are open circuiting any one of the port the Z-parameters Are called as open circuit parameters Got It ! Clear!
The ratio of apparent power to true power is called 'admittance', expressed in siemens. Admittance is the inverse of impedance.

the complete path that electricity can move through is called
Conductance is the reciprocal of resistance. If it is taken between one output parameter and one input parameter, then it is called transconductance i. e. the ratio of output current to the input voltage.It is given by gm= Iout/Vin

because they are involved in transmission lines
A parameter is a value that is used to carry out of task. It can be interpreted in a few ways. Parameters can be the values used to define filters if querying data in Excel. So if you have a list of data and want to show only some of it based on some criteria, that criteria can be referred to as parameters. If data is being read from an external source, it may require a parameter to define what data to show. Microsoft Access has something called a parameter query where a value is fed in at the time the query is run. That value is called a parameter. So if Excel is reading a parameter query from Access, it will need to provide a parameter to do it with. A parameter can be a value that is used in a function, though that is more commonly called an argument. In order for many functions to work they need values to work on. These are called arguments or occasionally parameters.
Every linear circuit having input and output terminals can be analysed by four parameters- 1 measured in ohms; - 1 measured in mho; - 2 are dimensionless are called h parameters. Hybrid means 'mixed'. Since these parameters have mixed dimensions, they are also called HYBRID PARAMETERS. These parameters are used to specify a transisitor performance conveniently for small voltages and currents in a particular circuit.
A formal perimeter refers to an identifier that is used in a method to stand for the value that is passed into the method by a caller. An actual perimeter on the other hand refers to the actual value that is passed into the method by a caller.
No. Function parameters are passed by value. Always. Even the so called "call by reference" is a value - the value of the pointer or the address of the object - but what is placed in the parameter list is a value.
Parameter
There are two ways to pass parameters to a method. 1) Pass by value 2) Pass by reference.(i.e. pass by pointers). For here, I would say, whenever you required to change the properties/value of the parameter by the method you called you should the approach (2). ie. pass by pointers.
Hybrid parameters are called so, because the parameters have different units. In Z- parameters, all the parameters have units of ohms and in Y- parameters, all parameters have Siemens as units. But in hybrid parameters, we have both ohms and Siemens as units. The other way it is called hybrid is, the independent variables are the input current and output voltage.
