Detailed Solution
Download Solution PDFसंकल्पना:
एका पूर्ण चक्रात ज्यावक्रीय तरंगाचे सरासरी मूल्य शून्य असते कारण दोन भाग एकमेकांना रद्द करतात, त्यामुळे सरासरी मूल्य अर्ध्या चक्रावर घेतले जाते.
\({V_{avg}} = \frac{1}{\pi }\mathop \smallint \nolimits_0^\pi {V_p}\sin \theta \;d\theta \)
\({V_{avg}} = \frac{{{V_p}}}{\pi }\left( { - \cos \theta } \right)_0^\pi \)
\({V_{avg}} = \frac{{2{V_p}}}{\pi } = 0.637 × {V_p}\)
म्हणून, ज्यावक्रीय तरंगाचे सरासरी मूल्य शिखर मूल्याच्या 0.637 पट आहे.
गणना:
दिले आहे,
Vavg = 12.74 V
\({V_{avg}} = \frac{{2{V_p}}}{\pi } = 0.637 × {V_p}\)
\(V_p=\frac{12.47}{0.637}~ V\)
= 19.57 V
∵ आपल्याला सर्वोच्च व्होल्टेज शोधण्यास सांगितले जाते.
∴ Vp-p = 2 × 19.57 ≈ 40 V
