What is the difference between AC and DC voltage?

AC (alternating current) voltage and DC (direct current) voltage are two different types of electric currents:

• AC Voltage: Alternates in direction and changes magnitude regularly. It is commonly used in household electrical devices and is more efficient for transmitting electricity over long distances.
• DC Voltage: Flows in one direction constantly. It is often used in batteries and electronic devices where a constant voltage is required.

In summary, AC voltage changes direction periodically while DC voltage flows in one constant direction.

Understanding the difference between AC and DC voltage is vital in the field of electrical engineering as it determines the applications and devices that can be used with each type of current.
