WebUse EWB instruments to measure voltage in an RC circuit. In a series RC circuit, the current leads the source voltage by a phase angle that depends on the resistance and the … WebThe total resistance of the RC series circuit in the AC circuit is called Impedance Z. Ohm's law applies to the entire circuit. The current is the same at every measuring point. Current and voltage are in phase at the ohmic resistance. The voltage rushes across the capacitive reactance of the capacitor after the current by −90 °.

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.
