Which component is associated with current leading voltage?

Current leading voltage is a phenomenon typically associated with capacitive elements in electrical systems. In a capacitor, the current reaches its peak before the voltage does, creating a phase shift where the current waveform leads the voltage waveform. This behavior is a defining characteristic of capacitors, as they store energy in an electric field and release it, which results in this leading current behavior.

In contrast, inductors exhibit current lagging behind voltage due to their nature of storing energy in a magnetic field. Resistors do not create any phase shift between current and voltage, as they simply dissipate energy without storing it. Generators, while they do produce voltage and current, do not inherently cause a leading relationship unless they are specifically designed to operate within a capacitive network. Thus, the association of current leading voltage is uniquely attributed to capacitors in this context.
