Question

Important: Show all procedure. 1. a. Using Thevenin's theorem, find the equivalent circult to the left of the terminals a and b in the circult shown below. Hence find I. 622 6 Ω a 48 V 8 A {40 122 b. Find the Norton equivalent circuit to the left of the terminals a and b in the circuit shown above. Either you can use Nortoo's theorem or use source transformation from Thevenin's circuit of part a.

Answer 1

Given cirmit diagram, or w 60 w GBV SA -an şls b To find the venin equivalent cirmit, have to find therenin voltage in series with thevenin resistance Apply Source Transformation for 488 and Art Gw M 480 + 448 şon a circuit is on M ji 48 6. Osa sun b ow M si Gr 8A b 67 73 6n GIGA sun In

Again apply source transformation technique 60 and 16 A for 64 m on GIGA 16x6 69 w on ti 96 :en 12~ li 96v b. Thevenin Voltage = open circuit voltage Vab = 964 4 4 +12 96x4 16 Thevenin's voltage = 24v To find thevenin resistance, short ciranit the offv. 12r in parallel to you .. Rth 12x4 12+ 4 48 16 Rene 34

Finally, equivalent circut is Rth=3r m li th=24v G i= th Rent! 24v 3+1 5. i 26 i=GA Nortons equivalent cirwit is obtained using thevenins equivalent aruit Rth= R Norton Rnor = 32 Norton current, in th rth in in= 24 3 Iin=8A Circuit is Ji in=&A 53. b
