Nothing. An overhead line is a set of conductors (most are aluminium) supported on wooden poles or steel pylons.
Capacitors can be used to improve power transmission if the load connected at the end of the line has a poor power factor. That happens for AC systems and for some types of load, electric motors for example, which need excess current over and above the power divided by the voltage.
The VA is the volts times the amps, and the actual power is the VA times the power factor, which never exceeds 1.
In some cases, a capacitor connected across the load can improve the power factor and therefore reduce the current that has to flow along the cables for a given amount of power.

How does surge impedance effect on transmittion line?
The SIL=(KV LL / Zo), where the V(LL) is the receiving end voltage in kV and Zo is the surge impedance in ohms. when the line is loaded over its SIL, it behaves like a shunt reactor - absorbing Mvar from the system, and when is loaded less its SIL it behaves like a shunt capacitor, supply Mvar back to the system. So to increase the Surge Impedance Loading (SIL), we need to decrease the the surge impedance of the line, and that can be done by introducing series capacitors (capacitors in series with the transmission line) or shunt capacitors (capacitors in parallel with transmission lines), which means providing Mvar to the system and reducing the Mw. hopefully that helps
What are the disadvantages of series capacitors in transmission lines?
The series capacitors can be the cause of overcompensating on the power line and thus cause the following problems:- a) Over voltages on the line when connected loads are smaller than the rated loads and this can damage the transformers and capacitors b) Ferro-resonace phenomenon can cause very high volatges again can be damaging c) The fault level of the poweer system will increase and if not considered in the design, the fault current could exceed thedesign limits.
What does a given line represent on a line graph?
the line on a line graph represents how things happen or improve over time. Like if we had several earthquakes in the past few weeks. The line will go up.
In rugby union does a line-out pass have to be over-head?
First of all, there are two types of lineouts: 1: Quick Lineout; No minimum of players need to be involved in a quick lineout, and you can only take a quick lineout immediatley after the ball goes into touch. A quick lineout DOES NOT need to be over-head. 2: Normal Lineout; There is a minimum of 3 players on each team for a normal line-out (usually more). A normal Lineout DOES need to be over-head*. *The reason a lineout should be taken over-head is that it is much easier to throw in a straight line.
What is the difference between a mohawk and a fohawk?

How can you improve your header technique in soccer?
A fun and exciting method of improving your headering ability could be through participating in football tennis. You can modify this drill my only using your head when attempting to get the ball over the net. Overtime this should improve your heading ability as your only using your head to get the ball over the net. Due to to this you will become more edept in using your head to attack and defend in match situations.
