127.4 V
141.4 V
282.8 V
200 V
Answer is Wrong!
Answer is Right!
The correct answer is A. 127.4 V.
The average value of a sine wave is equal to 0.637 times its peak value. This can be calculated using the following formula:
Average value = 0.637 Ã peak value
In this case, the peak value is 200 V, so the average value is:
Average value = 0.637 Ã 200 V = 127.4 V
Option B is incorrect because it is the RMS value of a sine wave. The RMS value is equal to 0.707 times the peak value.
Option C is incorrect because it is the peak-to-peak value of a sine wave. The peak-to-peak value is equal to twice the peak value.
Option D is incorrect because it is the peak value of the sine wave.
