Different between AC& dc

Question

Accepted Answer

AC and DC are two types of electrical current with different characteristics.

AC stands for alternating current, while DC stands for direct current.
AC changes direction periodically, while DC flows in one direction.
AC is commonly used in household appliances and power grids, while DC is used in batteries and electronic devices.
AC can be easily converted to different voltages using transformers, while DC requires converters or inverters for voltage conversion.
AC is more efficient for long-distance power transmission, while DC is more efficient for short-distance transmission.
Examples of AC devices include refrigerators, televisions, and air conditioners, while examples of DC devices include smartphones, laptops, and electric vehicles.

Accepted Answer
