Question

definition the primary constant line and secondary constant line
​

Answer 1

Answer:

$\huge \sf \gray {Primary \: Constant line}$

The primary line constants are only relevant to transmission lines and are to be contrasted with the secondary line constants, which can be derived from them, and are more generally applicable.

Answer 2

Answer:

Primary constant

The primary line constants are parameters that describe the characteristics of conductive transmission lines, such as pairs of copper wires, in terms of the physical electrical properties of the line.

Secendary constant

The secondary constants of a line are: Characteristic Impedance (Z0) Propagation Constant (γ) where γ=α+jβ the constants α=attenuation constant, β= phase constant. Since the line constants R, L, C, G are distributed through the entire length of the line, they are called as distributed elements.
