SUMMARY
The discussion centers on calculating the root-mean-square (Vrms) and average potential difference (Vav) for an AC power supply with a voltage amplitude of 45.0 V. The calculated Vrms is 31.82 V, derived from the equation Vrms = Vmax / √2. The average potential difference Vav is zero due to the symmetrical nature of the sinusoidal waveform, which results in equal positive and negative areas over one complete cycle. This conclusion is supported by examining the graph of alternating voltage versus time.
