If current leads voltage in a capacitive circuit, what does this relationship indicate?

In a capacitive circuit, when current leads voltage, this signifies a specific phase relationship between the two. The term "ELI" conveys that the voltage (E) lags behind the current (I) in an inductive circuit, while "ICE" suggests the current leads voltage in capacitive circuits.

This lead of current over voltage is indicative of capacitive reactance, which is rooted in the behavior of capacitors. In a capacitor, as the current flows, it charges the capacitor, thereby causing the current waveform to reach its peak before the voltage waveform does. Hence, the statement provides an insight into the inherent characteristics of capacitive components and their effect on the phase relationship of AC signals.

The other options do not appropriately represent the phase relationship observed in a capacitive circuit, as "R" refers to resistance, "Z" refers to impedance, and "ELI" pertains specifically to inductors and the lagging voltage relative to current. Therefore, the reference to "ICE" accurately captures the concept of current leading voltage in a capacitive scenario.
