for this circuit shown find the equivalent (total) resistance. show the work and assume all numbers are given to 2 significant digits

Rychme Ry Some Rohms 15 ohm Rg 20 mg d) 1Ω 2Ω 1Ω Λ 12Ω 4Ω. 10Ω 8Ω

Answer 1

solution, (a ) Given, Hare, Ri À R3 8 R2 Ra B 12. - 25.2 R₂=602 R₂ = 58 152 = 2022 R5 114 equivalent circuit, 123 Ra ww A B. C D Ri Rz 125 Resistance between point Cand D, Red (Rz + Ra) x R2 R₂ + R₂ TR4 (5+15)x60 60+5+15 15 R. Total equivalent Resistance, R=R1+Rcot Rg = 25+15+20 = GOR

d) equivalent circuit of given figure, 22 82 101 E C in 1212 B F G 42 Hare, 22 and 81 are in parallel combination with 101 Pesistance. Thus equivalent resistance, (2+8) X10 52 (10+2+8) RED so RED = 1 + Тlcp 6 r. (1+5)2 And REG 4X12X RED RED+4+12 4X12X6 6+12+4 13.092 Total equivalent resistance, 1 + 1 + 13.09 - 14.09r RAB REG
the answer is,

A) 60 ohm

D) 14.09 ohm
