No, the 0.30A mentioned on the charger is not the amplitude of its "real" draw current. In the context of an alternating current (AC) circuit, such as the one provided with the 230VAC 60Hz charger, the current is constantly changing direction and magnitude over time.
The value of 0.30A mentioned on the charger is most likely the average or nominal current rating. It represents the average value of the alternating current over a complete cycle. However, it does not indicate the peak or maximum current that the charger may draw during certain moments of the cycle.
To determine the actual peak or amplitude of the current, you would need more information or measurements. In an AC circuit, the current waveform typically follows a sinusoidal pattern. The peak or amplitude of the current waveform represents the maximum value reached during each cycle.
Therefore, without additional information, it is not accurate to state that 0.30A is the amplitude of the charger's current draw.
