Question

Find the current in the 24-resistor in the figure below. B А. B A E linn Lud He V A-60 B-12-02 Tc-70 D-24-0 TE-5-02 Let V = 18 volts 0.64 A 0.19 A 0.38 A 0.75 A None of the above

Answer 1

122 62 Equivalent resistance of two 12-12 resistere in Parallel is 122 12x12 12+12 ww] 242 O.TRA Aquivalent resistance of # FA and 242 resistore in Parallel is is ñ fig ~ 7x24 7+24 5.422 ww ww Equivalent resistance of the circuit is 5.422 52 1.55A * 0.79A 6+ [ (6+6) 11 (5-42+5) = 6+ [ 12 11 10.42 4 18V fig-2 a 6+ 12x10.42 12+10.42 a 6+ 5.57 11:57 2 Ia Řa 18 11.57 = 1.55 A Total current in the circuit 12-12 curreent Aureough 11:57 2 11:57a 1.55A 12 X 1.55A 12 +11.57 18V

079 A bftach branch So the total current in the lowere of Circuit circuit (in Hg 1) (in Fig 1) is 0.79A. aurrent through 24 oe is 7 X 0.79 A 24+7 a 77 x 0.7 x 0.79 A 31 0.18 A נו So the current through 242 is 0.18 A which is so and option is correct. nearly 0.19 A
