A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.

• Transformers work on the principle of electromagnetic induction

• They have two coils, primary and secondary, which are wound around a common magnetic core

• When an alternating current flows through the primary coil, it creates a magnetic field which induces a voltage in the secondary coil

• Tran...read more

Skin effect is the tendency of high-frequency current to flow near the surface of a conductor.

• It occurs due to the self-inductance of the conductor.

• It increases with frequency and decreases with the diameter of the conductor.

• It can cause power loss and heating in high-frequency applications.

• It is important to consider in designing high-frequency circuits and transmission lines.

• Examples include radio antennas and high-f

The material used in a 1km Ht line depends on various factors such as voltage, weather conditions, and budget.

• The voltage of the line determines the type of conductor material used, such as aluminum or copper.

• Weather conditions can also affect the choice of material, with some materials being more resistant to corrosion or extreme temperatures.

• Budget is also a factor, with some materials being more expensive than other...read more
