  • The peak voltage of an ac supply is 300 V. What is the rms voltage?

Q7.2 (a) The peak voltage of an ac supply is 300 V. What is the RMS voltage?

Answers (1)

best_answer

Given

Peak Value of ac supply:

 V_{peak}=300V

Now as we know in any sinusoidal function

 RMSvalue=\frac{peakvalue}{\sqrt{2}}

Since our ac voltage  supply is also sinusoidal

V_{rms}=\frac{V_{peak}}{\sqrt{2}}=\frac{300}{\sqrt{2}}=212.13V

Hence RMS value of voltage os 212.13V.
