B)साइन वेव [Sine wave]
C)हाफ वेव रेक्टिफाइड साइन वेव [Half wave rectified sine wave]
D)त्रिकोणीय वेव [Triangular wave]
Answer: C)हाफ वेव रेक्टिफाइड साइन वेव [Half wave rectified sine wave]
Detailed Solution
Form Factor is the ratio of the RMS value to the average value.
Form Factor = rms value / average value
The half-wave converted sine wave has the highest value of the form factor.
Calculation:
RMS value = Vm /2
Average value = Vm/π
Average value = Vm/π
Form Factor = (Vm x π) / (2 x Vm) or π/2 or 3.142 /2 =1.57
The table of the form factors of wave forms is given below:
- Waveform RMS Value Form Factor
- Sine Wave 0.707 1.11
- Triangular Wave 0.577 1.154
- Square Wave 1 1
- Sawtooth Wave 0.577 1.154
- Half wave rectified 1.57
