The standard unit of measurement for electricity is the Ampere, often shortened to "Amp." It is used to quantify the flow of electric current in a circuit. One Ampere represents a flow of one coulomb of electrical charge per second. This unit is a critical component in understanding electrical systems, as it helps define how much electric charge is moving through a conductor. The Ampere is part of the International System of Units (SI), and it plays a significant role in electricity-related calculations, including power consumption and circuit design, alongside other units like volts and ohms.
