Question

What are the 4 basic parameters of transmission line?

Answer 1

The four basic parameters of a transmission line are:

1. Resistance (R): This represents the opposition to the flow of electric current in the transmission line. It is caused by the material of the conductors and leads to energy loss in the form of heat.
   

1. Inductance (L): This parameter describes the ability of the transmission line to store energy in a magnetic field when current flows through it. Inductance causes a delay in the response of the current to changes in voltage.
   

1. Capacitance (C): This refers to the ability of the transmission line to store energy in an electric field between the conductors. It is caused by the potential difference between the conductors and leads to the transmission of power between the conductors.
   

1. Conductance (G): This is the leakage current that flows through the insulating material between the conductors. It represents energy loss due to imperfect insulation.
   

These parameters (R, L, C, and G) are essential for analyzing and designing transmission lines for proper signal or power transmission.
