Question

Question 2 [4 Mark (0.2 mark each)] Fill-in the answer in the given blank below (Hint: Use the below table to organize your answer). For the network shown in the figure, determine 1) The voltage drop on each element 2) The current through each elements and its direction 64 (note that, use the circuit to show the direction) 3) Determine Rr by combining resistive elements. 4) Use the found current in 2) to calculate Is 5) Determine Rīfrom Rra, 6) Compare Rşin part 5) and 3) (0.2 mark) mihin R1 R2 R3 R4 R5 R6 R7 R8 RT, Is Part 4) Part 3) R 162 822 422 32 22 162 822 16 22 822

Answer 1

w wm Ro R2 dBA TRA 4A w + 2 R3 ANGA 640 = E AARS A -04 >On = 162 R2 = 8n 42 RA= B2n 11 10 11 RS=162 R6 = 8 R = 162 Q 8= 8 i Node bb es reference (ie, ovy Let the potential at made a bir be Na, vet is vb zor < leefertence Node) How applying Nodal analyres at Va ----V6 = 64 . I va = 64v! e, nollage drop across Rq = Na-ve= 64v voltage drop across R2 = varve = 640 Nollage drop achoy Az = varve = 641 voltage dreop acron RA = Na avf= 64 acheous Voltage drop Rss Va-V6 = 648 Voltage drop across R6 = Vanva= or Voltage drop across R7 = va-va = or Voltage drop across Rs = v = or

ALB Current through R, E va-ve = 64 = 44, Current through 64 = 8A jo Rq = va-vb = Rr Ros= VQ-vb - Current through - 16A - slt 2A Current through olisivat current through 4A Current Current through through Rs = va-vb- = 1 Rs R6 = va-va = OA Ry = vezava - On R8 = Voord - of current intrough @ R6 {RR at RL 23 R8 ) * R Rg circuited & Rp are short 3 R
