Which of the following is NOT the parameter/s of the transmission line...
Introduction:
Transmission lines are used to transmit electrical energy or signals from one place to another. They are used in various applications such as power transmission, telecommunication, and networking. Transmission lines have certain parameters that define their characteristics and behavior. These parameters include resistance, inductance, capacitance, and conductance.
Explanation:
In the given options, the parameter that is NOT a part of the transmission line is series capacitance. Let's understand why.
Resistance (Option B):
Resistance is a parameter that represents the opposition to the flow of electrical current in a transmission line. It is caused by the conductor material and contributes to power loss in the form of heat. Resistance is an essential parameter to consider in transmission line analysis.
Inductance (Option C):
Inductance is a parameter that represents the ability of a transmission line to store energy in a magnetic field. It occurs due to the magnetic field generated by the current flowing through the conductors of the transmission line. Inductance affects the impedance and propagation characteristics of the transmission line.
Capacitance (Option D):
Capacitance is the ability of a transmission line to store energy in an electric field. It occurs between the conductors of the transmission line and the surrounding environment. Capacitance can cause voltage imbalances and affect the propagation characteristics of the transmission line.
Shunt Conductance (Option A):
Shunt conductance is a parameter that represents the leakage of current from the transmission line. It is caused by the insulation properties of the transmission line and its surroundings. Shunt conductance contributes to power loss and affects the overall performance of the transmission line.
Conclusion:
Among the given options, the series capacitance is NOT a parameter of the transmission line. Resistance, inductance, and shunt conductance are all important parameters to consider when analyzing the behavior and characteristics of transmission lines.

Which of the following is NOT the parameter/s of the transmission line...
Components or Parameter of Transmission Line:
- A transmission line has three constants R, L, and C distributed uniformly along the whole length of the line.
- Note: There is also a fourth constant i.e., shunt conductance. It represents the conductance between conductors or between conductor and ground and accounts for the leakage current at the insulators. It is very small in the case of overhead lines and may be assumed zero.
- The resistance and inductance form the series impedance.
- The capacitance existing between conductors for a 1-phase line or from a conductor to neutral for a 3-phase line forms a shunt path throughout the length of the line.
- Therefore, capacitance effects introduce complications in transmission line calculations
- The leakage conductance takes into account the energy losses occurring through leakage over the insulators or due to the corona effect between conductors.
- The leakage current through shunt admittance is maximum at the sending end of the line and decreases continuously as the receiving end of the circuit is approached at which point its value is zero
Important PointsThe following points may be noted:
- The line constants are uniformly distributed over the entire length of the line as is actually the case.
- The resistance and inductive reactance are the series elements.
- The leakage susceptance (B) and leakage conductance (G) are shunt elements. The leakage susceptance is due to the fact that capacitance exists between line and neutral.
