In measuring phase change for a monophasic waveform, what is the standard unit of measure?

In assessing phase change for a monophasic waveform, the standard unit of measure is Coulomb. The reason for this is that Coulombs quantify electric charge, which is essential in understanding the characteristics of an electrical waveform, including its phases. In this context, each phase of a monophasic waveform corresponds to a specific manner in which the charge behaves in relation to time, and measuring the amount of charge passing through a conductor is critical in understanding these phases.

The other options do not directly relate to phase measurement in the context of waveforms. The Ampere refers to the flow of electric current, which is about the rate of charge flow, but not specifically the measurement of phase change. Ohms refer to resistance, which does not apply to the measurement of electrical phases directly. Seconds measure time, which is relevant for understanding the duration of a waveform but does not encompass the fundamental measurement of the charge involved in phase change.
