Read the following excerpt:

"The conductor cables constitute the actual active elements of the transmission lines and must therefore possess special characteristics. Their proper choice represents a problem of fundamental importance in line design, as it has important implications of an economic nature. Ideal conductors for overhead transmission lines would be those that could reduce some undesirable effects that occur in the transport of electrical energy, such as the skin effect, capacitive effect, corona, and ohmic losses."

Considering this information and the content studied about the electrical phenomena intrinsic to the physical and operational characteristics of power transmission lines, analyze the following statements and associate them with their respective phenomena:

1) Skin effect.
2) Capacitive effect.
3) Corona effect.
4) Effect caused by aluminum resistance.

( ) Effect caused by the influence of line inductance and which varies with frequency.

( ) Effect that can cause voltage elevation along transmission lines.

( ) Effect that can be observed at the ends of the insulator chains of transmission lines.

( ) Responsible for heating the cables of transmission lines.
