Difference Between AC and DC Electricity

AC (alternating current) and DC (direct current) are two types of electrical currents used in various applications. The main difference between AC and DC electricity lies in the direction the current flows and the way voltage is supplied.

• Direction: AC electricity changes direction periodically, typically 50 to 60 times per second. In contrast, DC electricity flows in a continuous direction from the positive to the negative terminal.
• Voltage Supply: AC electricity is generated using a rotating generator that produces a sinusoidal voltage. DC electricity, on the other hand, is typically supplied by batteries or solar cells where the voltage remains constant.
• Applications: AC electricity is commonly used in homes, businesses, and power grids due to its ability to be easily converted and transmitted over long distances. DC electricity is often used in electronic devices, such as computers, phones, and electric vehicles.

Understanding the differences between AC and DC electricity is crucial for electrical engineers and professionals working in the field of electrical engineering.
