Question

0.2500 62 5 + 20 +18 V Given a complex circuit in Figure Q1. This complex circuit is to be viewed in a simpler form of Thevenin and Norton equivalent circuits a) Dengan menggunakan analisis nod, cari voltan Thevenin, Vrh di terminal a dan b. By applying Nodal analysis, find Thevenin voltage, Vru al terminal a and b. (4 markah/marks) b) Sekiranya terminal a dan b dibiarkan bersambung, tentukan nilai semasa arus yang melalui terminal tersebut, iaitu Isc. Berikutan itu, tentukan rintangan Thevenin, RTH dan arus Norton, In bagi litar ini. (Pembayang: Gunakan Mesh analisis; Rru = VTH: IN TH) Let terminal a and b connected. At this condition, determine the value of current passing through the terminal, ie Isc Following that, determine Thevenin resistance, Rth and Norton current, In for the circuit. (Hint: Apply Mesh analysis; RTH TH IN TH) (8 markah/marks) .) Berdasarkan penemuan dalam a) dan b), lakarkan litar Thevenin dan Norton yang setara. Apakah hubungan antara dua litar setara ini? Based on your findings in a) and b), draw equivalent Thevenin and Norton circuits. What is the connection between these two equivalent circuits?

Given circul :- : 0-25 Vo 6.2 w an 18v 30 vo @ By nedal Analysis at ė :- 18 - Yo +0.36V = V +0.95 18 = Votvo Vo - is cov

VTH Vab = (-0.25%+a] +Vo VHF (-0.256+2] + 6 0.25 Vo 21 By mesh analysis 18 = 61, +3[1, -Ise] 18-91, -31sc —0 0 = [0.25 Vo +Ise] + 3(Tse-1,] Vo = 3 [Ige+I,] iw 0 - 0.543[1,-Ise]+2 Tsc + 315c – 31, 03 -1.51, +3.5 Ise —- By solving and 9: - @*6 => 0 = -971, +91 Isc 18: 94 – 3 Isc 18 = 18 Tsc Iscala
