Q. आर.एम.एस. के मामले में मान और माध्य मान समान हैं?

A)त्रिकोणीय वेव [triangular wave]
B)साइन वेव [sine wave]
C)स्क्वेर वेव [square wave]
D)हाफ वेव रेक्टिफाइड साइन वेव [half wave rectified sine wave]

Answer. C)स्क्वेर वेव [square wave]

 

Conceptual Detailed Solution

The RMS value (Vrms) is related to the peak value (Vm) for different waveforms as:

      Waveform                            RMS value
  1. Sine wave                        Vm / √2
  2. Sawtooth wave                Vm / √3
  3. Triangular wave               Vm / √3
  4. Square wave Vrms           Vm
