Electric Current Overview

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

Ohm’s Law Overview

In 1827, German physicist Georg Ohm published a groundbreaking paper that would come to be known as Ohm’s law. In it, he described the relationship between voltage, current, and resistance in electrical circuits. This simple yet powerful equation has since become one of the most fundamental principles of physics and has countless applications in the… Read More
