Which of the following is like equivalent circuit of medium transmissi...
The equivalent circuit of a medium transmission line is an RLC circuit in pie form.Explanation:
The transmission line is a long conductor used for transmitting electrical power or signals from one point to another. A medium transmission line is a transmission line with moderate length, typically between 80 km and 250 km.
To represent the behavior of a medium transmission line, an equivalent circuit is used. This equivalent circuit consists of lumped elements that represent the electrical characteristics of the transmission line.
Series RLC Circuit:
A series RLC circuit consists of a resistor (R), an inductor (L), and a capacitor (C) connected in series. In this circuit, the resistor represents the resistance of the transmission line, the inductor represents the inductance of the transmission line, and the capacitor represents the capacitance of the transmission line.
However, a series RLC circuit does not accurately represent the behavior of a medium transmission line because it does not take into account the distributed parameters of the transmission line, such as the distributed resistance, inductance, and capacitance.
Series RL Circuit:
A series RL circuit consists of a resistor (R) and an inductor (L) connected in series. This circuit also does not accurately represent the behavior of a medium transmission line because it does not consider the distributed capacitance of the transmission line.
Parallel RL Circuit:
A parallel RL circuit consists of a resistor (R) and an inductor (L) connected in parallel. This circuit also does not accurately represent the behavior of a medium transmission line because it does not take into account the distributed resistance and capacitance of the transmission line.
RLC Circuit in Pie Form:
The RLC circuit in pie form is the most accurate representation of the behavior of a medium transmission line. It consists of a resistor (R), an inductor (L), and a capacitor (C) connected in a specific configuration.
In the RLC circuit in pie form, the resistor represents the distributed resistance of the transmission line, the inductor represents the distributed inductance of the transmission line, and the capacitor represents the distributed capacitance of the transmission line.
This circuit accurately models the propagation characteristics of a medium transmission line, including the effects of attenuation, distortion, and reflection.
Therefore, the equivalent circuit of a medium transmission line is an RLC circuit in pie form.
