Download Solution PDFধারণা:
একটি সম্পূর্ণ চক্রের সাইনোসয়েডাল তরঙ্গরূপের গড় মান শূন্য হয় কারণ দুটি অর্ধ একে অপরকে বাতিল করে দেয়, তাই গড় মানটি অর্ধ চক্রের উপর নির্ভর করে গৃহীত হয়।
\({V_{avg}} = \frac{1}{\pi }\mathop \smallint \nolimits_0^\pi {V_p}\sin \theta \;d\theta \)
\({V_{avg}} = \frac{{{V_p}}}{\pi }\left( { - \cos \theta } \right)_0^\pi \)
\({V_{avg}} = \frac{{2{V_p}}}{\pi } = 0.637 × {V_p}\)
অতএব, সাইনোসয়েডাল তরঙ্গের গড় মান সর্বোচ্চ মানের 0.637 গুণ হয়।
গণনা:
প্রদত্ত,
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
∵ আমাদের শীর্ষ থেকে শীর্ষ ভোল্টেজ নির্ণয় করতে বলা হয়েছে।
∴ Vp-p = 2 × 19.57 ≈ 40 V
