For a sine wave with peak value Imax the r.m.s. value is?

 

Q. शिखर मान आईमैक्स वाली साइन तरंग के लिए आर.एम.एस. मान है?

A)0.5 इमैक्स [0.5 Imax]
B)0.707 आईमैक्स [0.707 Imax]
C)0.9 आईमैक्स [0.9 Imax]
D)1.414 इमैक्स [1.414 Imax]

Answer: B)0.707 आईमैक्स [0.707 Imax]

 

Detailed Solution

The RMS value (Vrms) is related to the peak value (Vm) for different waveforms as: RMS मान (Vrms) विभिन्न तरंगों के लिए शिखर मान (Vm) से संबंधित है:

      Waveform                            RMS value
  1. Sine wave                        Vm / √2 = 0.707
  2. Sawtooth wave                Vm / √3 = 0.577
  3. Triangular wave               Vm / √3 =0.577

  4. Square wave Vrms           Vm = 1
