Difference Between AC and DC Current in Electrical Engineering

In electrical engineering, the main difference between AC (alternating current) and DC (direct current) lies in the direction and flow of the electric charge. AC current reverses its direction periodically, while DC current flows in one direction consistently.

AC is commonly used in households and most electrical devices, while DC is often used in batteries and electronic circuits. AC is known for its efficient energy transmission over long distances, while DC is preferred for its ability to store energy in batteries.

Difference Between AC and DC Current in Electrical Engineering

Alternating Current (AC) and Direct Current (DC) are two different types of electrical currents that are commonly used in electrical engineering.

AC Current:

• AC current changes direction periodically.
• It is generated by power plants and is used to distribute electricity over long distances.
• AC current can be easily transformed and converted to different voltage levels.
• Common frequency for AC current is 50 Hz or 60 Hz.

DC Current:

• DC current flows in one direction only.
• It is commonly used in batteries and electronic devices.
• DC current does not change its voltage level easily.
• DC current is typically more stable compared to AC.

Overall, the main difference between AC and DC current lies in the direction of the flow and the applications they are used for in electrical engineering.
