Answer 2

Heya Bro,

Uses of AC current :

AC is the primary format for power and signal transmission.

Of course, power coming into your home is AC, cell phones, radios, and microwave ovens transmit and/or receive AC in the bands called RF (radio frequency) and microwave.

Here’s one more you may not have thought of: infrared, visible light, and ultraviolet. At those frequencies, it is more convenient to note the wavelength instead of the frequency. However, infrared, visible light, and UV are all alternating current, electromagnetic radiation as well.
