Question

Part A Find the currents through each resistor in the circuit shown on the diagram (Figure 1). Use the following values: E = 12.0 V, R1 = 35.0 N2 , R2 = 22.0 N2 , R3 = 41.0 12 , and R4 = 14.02. The circuit drawing is already given in the problem introduction. However, you can redraw this circuit to make it easier to reduce to a circuit with a single equivalent resistor. Which of the following circuits is equivalent to the circuit given in the problem? Check all that apply. Figure < 1 of 1 ZR
which of these circuits are equivalent to the figure?

Answer 1

Given that - R3 352 ZR1 R2 & 222 - 12V RU It can be redrawn as- uir If VI R3 R2 3222 Ra3 222 Ry I-IN 12v य by KVL- 12-22 I-35 I1=6 or 22I+3571=12-① RUL- 3571 - (I-II (untius20 or 35 In - 55 (I-I1=0

or - rut goli = 551 or I = 11/187 or I = 1.63611- I value in eq- - - (2)(1-636 11 ) +3571-12 7271312 =) ZLEVGA and I t XII I = 11XZI 18 Z = 1 x 1 - 18 G [Z= 0.10185A 1 168 So current through R2 is IZAIGA Current through & Riis I1 = 0-10185A current through Ro and Ruis z-Z1 = /G-0-10185 or z-I = 0.0648A Equivalent circuit is- I R3 Ry
