Which one of the following is correct?

Correct answer: A. V0=1.414 Vrms

  • A. V0=1.414 Vrms
  • B. Irms=1.414 Io
  • C. V0=10.70 Vrms
  • D. Both A and B

Explanation

This statement is correct. V0 represents the peak value of an alternating voltage, while Vrms represents the root mean square (RMS) value of that voltage. The relationship between the peak value and RMS value in an ideal sinusoidal waveform is V0 = 1.414 Vrms. This is a fundamental relationship in A.C. circuit analysis. Vrms=0.707V0 So V0=1/0.707 Vrms=1.414 Vrms

About Alternating Current

Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
