What is the difference between AC and DC?
AC (alternating current) and DC (direct current) are two different types of electrical current. The main difference between the two is the direction in which the current flows.
- AC: Alternating current changes direction periodically. It flows in one direction for a period of time, then reverses and flows in the opposite direction. This type of current is commonly used in homes and businesses, as it is easy to generate and can be easily transformed into different voltages.
- DC: Direct current flows in one direction only, from the positive terminal to the negative terminal. This type of current is commonly used in batteries and electronic devices, as it provides a consistent flow of electricity.
Overall, AC is typically used for transmitting electricity over long distances, while DC is more commonly used in electronic devices and for powering small appliances.
