Amperét

Amperét is a unit of electric current in the International System of Units (SI). It is named after the French physicist André-Marie Ampère. One amperét is defined as the flow of one coulomb of electric charge per second. This means that if one coulomb of charge passes a point in a circuit in one second, the current is one amperét. The symbol for amperét is A. Electric current is the rate at which electric charge flows past a point. It is a fundamental quantity in electricity and magnetism. The amperét is used to measure the strength of electric currents in various applications, from household appliances to industrial machinery. For example, a light bulb might draw a current of 0.5 amperét, while a powerful motor could draw several hundred amperét. The unit is essential for understanding and calculating electrical power and resistance, often used in Ohm's Law (V=IR) and the power formula (P=VI).
