Electric current is the rate of flow of electric charge. The SI Unit of electric current is the Ampere, which is equal to a flow of one coulomb per second. Electric current can be either direct or alternating. Direct Current (DC) flows in one direction only, while Alternating Current (AC) changes direction periodically. Electric currents… Read More

In 1831, Michael Faraday discovered that when a conductor is moved through a magnetic field, an electric current is produced. This discovery led to the development of alternating current (AC), which alternates the direction of the current and can be transmitted over long distances. AC is more efficient than direct current (DC) because it can… Read More
