Amperios, or amperes, are the standard unit of electric current in the International System of Units (SI). One ampere is defined as the flow of one coulomb of electric charge per second. This measurement helps us understand how much electricity is flowing through a circuit at any given time. In practical terms, amperios are crucial for determining the capacity of electrical devices. For example, a light bulb rated at 2 amperes will draw that amount of current when connected to a power source. Understanding amperios is essential for safely designing and using electrical systems.
