Electrical energy can travel along a simple electrical circuit or along a transmission line, or by electromagnetic radiation. AC power usually refers to power at a single frequency, for example 50 Hz or 14 MHz.
Power travelling along a transmission line loses a fixed proportion of its intensity per unit length of the line. By contrast, power travelling by electromagnetic radiation loses three quarters of its power density every time the distance is doubled. Therefore of the two methods electromagnetic radiaton can travel a lot further.

How is AC electricity different from static electricity?
AC (alternating current) electricity constantly changes direction and magnitude in a circuit, typically in a sine wave pattern. Static electricity, on the other hand, refers to an imbalance of electric charge on the surface of an object. AC electricity is used for powering devices and transmitting electricity over long distances, while static electricity is typically seen in everyday scenarios like when you rub a balloon on your hair.
