Give an example of a use of AC power other than in the household. Similarly, give an example of a use of DC power other than that supplied by batteries.

AC power is generated by current flowing in both directions, whereas DC power is generated by current flowing in only one direction.

A high-frequency alternating current (AC) is used for the purpose of burning skin warts, as a matter of fact, that a high-frequency current does not penetrate inside the skin but travels on the surface of the body only, also alternating current is used in ventricular fibrillation.

AC power supply is an alternating current with a frequency of \(50{\rm{ }}{\mathop{\rm Hz}\nolimits} \)and a potential difference of \(230{\rm{ }}{\mathop{\rm volts}\nolimits} \) that is utilized in frequency generators for communication.

An alternating current is transformed into a direct current (DC), with the help of a rectifier and used for several purposes like automobiles.

They required \(12{\rm{ }}{\mathop{\rm V}\nolimits} \) DC, so there is an alternator in automobiles that converts AC to DC for such purpose.

In the home, a DC power source with a low potential difference is employed in phone chargers.
