Alternating current (AC) and direct current (DC) are the two fundamental types of electrical current used for power distribution and in electrical circuits. While AC changes direction periodically and is commonly used for power grids due to its efficiency in long-distance transmission, DC flows in one constant direction and is typically used in battery-powered devices and electronics.

AC And DC Current

Alternating current (AC) is an electric current that periodically reverses direction, in contrast to direct current (DC) which flows only in one direction. AC is the form of electrical power that is delivered to homes and businesses, and it is the form of electrical energy that consumers typically use when they plug appliances into a wall socket.

Alternating Current

Direct current (DC) is the unidirectional flow of electric charge, typically produced by sources such as batteries, solar cells, and DC generators. It is essential for powering electronic devices, charging batteries, and is used in applications requiring stable and constant voltage levels.

Direct Current

Types of electrical current

Power distribution is the process of delivering electricity from the transmission system to individual consumers, ensuring reliable and efficient energy flow across the grid. It involves a network of substations, transformers, and distribution lines that operate at lower voltages to meet residential, commercial, and industrial energy demands.

Power Distribution

Electrical circuits are pathways that allow electric current to flow, typically composed of various electrical components like resistors, capacitors, and inductors. Understanding the principles of voltage, current, and resistance is essential to analyze and design circuits effectively.
