Vooluhoovad

Vooluhoovad refers to the flow of electric current. It is the measure of the rate at which electric charge passes through a surface or a point. This flow is caused by the movement of charged particles, typically electrons in conductors, but can also involve ions in electrolytes or plasmas. The standard unit for measuring electric current is the ampere (A), named after the French physicist André-Marie Ampère. One ampere is defined as one coulomb of electric charge passing a point per second.

Electric current can be broadly categorized into two types: direct current (DC) and alternating current (AC). In direct current, the charge flows consistently in one direction. Batteries and solar cells are common sources of DC. Alternating current, on the other hand, periodically reverses direction. The electric power supplied to homes and businesses is typically AC, generated by power plants and transmitted over long distances.

The magnitude of electric current is crucial in many applications. It determines the power delivered by an electrical device, the strength of magnetic fields produced by electromagnets, and the amount of heat generated in a resistor. Understanding vooluhoovad is fundamental to the study of electricity and electronics, enabling the design and operation of countless technologies that shape modern life.
