Webthe capacitor, the voltage across the capacitor “lags” the current by 90° in phase, meaning that the voltage peaks occur one-fourth of an oscillation period after the current peaks. This relationship is illustrated in Figure 10.2, where the voltage across the resistor (V R) shows the variation of current during a single cycle. WebThe RMS voltage is otherwise called the same DC voltage on the grounds that the RMS esteem gives how much AC power is drawn by a resistor like the power drawn by a DC source. For instance, take a 5ω burden associated with a 10V DC source. On account of the DC source, the worth of voltage is consistent for each moment of time.
