Final answer:
The peak voltage (Vpeak) for a supply voltage of 100 V RMS in an AC circuit is found using the relationship Vpeak = Vrms * √2, resulting in a Vpeak of 141.42 V.
Step-by-step explanation:
If the supply voltage is 100 V, we need to determine the peak voltage (Vpeak). The supply voltage typically refers to the root mean square (RMS) voltage in AC circuits, which represents the equivalent DC voltage that would provide the same power to a load as the AC supply. To find the peak voltage, which is the maximum voltage reached by an AC waveform, we use the relationship Vpeak = Vrms * √2.
For a supply voltage (Vrms) of 100 V, the peak voltage (Vpeak) is calculated as:
Vpeak = 100 V * √2
Vpeak = 100 V * 1.4142
Vpeak = 141.42 V.
Therefore, the correct option is B.141.42 V, which represents the peak value of an AC waveform with an RMS voltage of 100 V.
