Leading current In circuits with primarily capacitive loads, current leads the voltage. This is true because current must first flow to the two plates of the capacitor, where charge is stored. Only after charge accumulates at the plates of a capacitor is a voltage difference established.

Web"Lead" and "Lag" reflect the relative timing of two signals. If func1 has a peak sooner than func2, we say func1 leads func2. In these graphs, time increases as you go to the right. So a time near the origin happens sooner than a time out to the right on the time axis. If you look at the cosine function, it has its peak at t = 0. diabetic shoes mcminnville tnWebUse EWB instruments to measure voltage in an RC circuit.
