Haya Jozee, hebu tutatue hili. a) Andika mlinganyo wa thamani ya papo hapo. Step 1: Tambua vigezo vilivyotolewa. Tunapewa: Thamani ya juu zaidi ya mkondo (maximum current), I_0 = 120 A Marudio (frequency), f = 60 Hz Mkondo unaanzia sifuri na kuwa chanya, hivyo tunatumia kazi ya sine. Step 2: Andika mlinganyo wa jumla wa mkondo wa papo hapo. Mlinganyo wa mkondo wa papo hapo (instantaneous current) ni: I = I_0 (2 ft) Step 3: Badilisha thamani za I_0 na f kwenye mlinganyo. I = 120 (2 × 60t) I = 120 (120 t) Mlinganyo wa thamani ya papo hapo ni I = 120 (120 t). b) Tafuta mkondo wa papo hapo baada ya sekunde 1/360. Step 1: Tumia mlinganyo kutoka sehemu (a). I = 120 (120 t) Step 2: Badilisha thamani ya muda t = (1)/(360) s kwenye mlinganyo. I = 120 (120 × (1)/(360)) Step 3: Rahisisha na kokotoa thamani ya I. I = 120 ((120)/(360)) I = 120 (()/(3)) Tunajua kuwa (()/(3)) = (60^) = sqrt(3)2. I = 120 × sqrt(3)2 I = 60sqrt(3) A Thamani ya mkondo wa papo hapo ni 60sqrt(3) A. 3 done, 2 left today. You're making progress.
