Alternating current

Alternating current(AC) is an electrical current that sporadically reverses direction, whereas DC (DC) flows solely in one direction.

alternating current -Acelectrical energy is that the type within which power is delivered to businesses and residences, and it’s the shape of current that buyers generally use once they plug room appliances, televisions and electrical lamps into an electric outlet. a standard supply of DC power could be a battery cell during a torch.



 

The abbreviations AC and DC are typically accustomed mean merely alternating and direct, as once they modify current or voltage.

The usual undulation of electrical energy in most power circuits could be an undulation. Ensure applications, completely different waveforms are used, like triangular or SQ. waves.

Audio and radio signals carried on electrical wires are samples of electrical energy. These styles of electrical energy carry data encoded (or modulated) onto the AC signal, like sound (audio) or pictures (video).

These currents generally alternate at higher frequencies than those utilized in power transmission.
