Answer 1

- because Req=0 shoat clacuit blo A & B. parallel to y resistance Zero Resistance (shoat cigcut) equalent to zero resistance. 3002 Series -$15 10 23 OB 241 - + 30 +72 +24 20 -R R2 R - +- 10 30 gu Restorano ~ 24 F = 5.7142n Series / -Parallel = 30x30 30+30- - 152 oB o pelallel 15X80 15+30 450 15x30 15+36 = 102

In this question, balance occurs so there is no current flow in not resistor then cwluch can be simply eliminate va po Balanced - y z=xw | 3x6 = 3x6 so us neglected. 6x12 = 42 Req- 6+12 54 In this question , unbalanced condition - Ý there 1x4 & 1x1 so 32 can not be neglected use Y-A (64) A to Y Transformation Techniques for such questions CA BCC b AB ATBtc A+Btc. d + +R A A + Btc S sú a = 9341 bar c=5
