The term 'current' in electrical terminology specifically refers to the flow of electric charge. It is measured in amperes (A) and represents the movement of electrons through a conductor. This movement is driven by the voltage supplied to the circuit, which creates an electric field that pushes the charge carriers—typically electrons—from one point to another.

Understanding current is essential as it directly influences the overall functionality of electrical systems. For example, in a closed circuit, the amount of current determines how much power is delivered to devices. This flow is fundamental in all electrical applications, as it enables devices to operate and perform their intended functions.

Other terms provided in the question relate to different aspects of electrical systems. The stored energy in a capacitor represents a completely different concept, focusing on the energy potential rather than the flow. The pressure exerted by the electrical supply refers to voltage, which pushes the current through the circuit. Lastly, resistance pertains to the opposition to current flow, affecting how much current actually flows in the presence of a given voltage. Understanding these distinctions is vital for a comprehensive grasp of electrical principles.
