Impedance is a measure of the opposition to current flow in an electrical circuit. It is represented by the letter (Z) and is measured in ohms. Impedance includes resistance, but also takes into account reactance, which is the opposition to current flow due to inductive or capacitive effects. The impedance of a circuit can be… Read More

Electric resistance is the measure of a material’s opposition to the flow of electric current. The higher the electric resistance of a material, the more it opposes the flow of current. Electric resistance is measured in ohms. Materials with high electric resistance are used in electrical circuits as resistors. Resistors are used to control the… Read More

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
