If the height of transmission tower is increased:a)the line capacitanc...
Explanation:

When the height of a transmission tower is increased, it affects the line capacitance and inductance. The line capacitance is the ability of the line to store electric charge, while the line inductance is the ability of the line to store magnetic energy. The relationship between the height of the transmission tower and the line capacitance and inductance is explained as follows:

Effect on line capacitance:
- The capacitance of a transmission line is directly proportional to the spacing between the conductors and inversely proportional to the height of the tower.
- When the height of the tower is increased, the spacing between the conductors remains the same, but the distance between the conductors and the ground increases.
- As a result, the capacitance of the line decreases because the electric field between the conductors and the ground weakens.

Effect on line inductance:
- The inductance of a transmission line is directly proportional to the height of the tower and inversely proportional to the spacing between the conductors.
- When the height of the tower is increased, the distance between the conductors and the ground increases, but the spacing between the conductors remains the same.
- As a result, the inductance of the line remains unchanged.

Conclusion:
Based on the above explanation, we can conclude that when the height of the transmission tower is increased:
- The line capacitance will decrease because the distance between the conductors and the ground increases.
- The line inductance will remain unchanged because the spacing between the conductors remains the same. Therefore, option 'C' is the correct answer.

Concept:
  • The inductance of a transmission line is independent of the height of the transmission tower.
  • The capacitance of the transmission line is dependent on the height of the transmission tower.
  • If tower height increases then the distance between the current carrying wire and ground increases, and line-to-ground capacitance decreases, as capacitance is inversely proportional to the distance between the line and earth.
  • While there is no effect on line to line capacitance.
