Problem # 5 A circuit is shown on the right. a R, = 20 2 b R3 = 802 C a) Write the Kirchhoff's 1 st rule (junction rule) 1 = 0.5 0 for Junction b. Is there any new information R2 = 60 gained by applying the junction rule at 82 - 3.0 V Junction e? 12 V 0.5 0 & = 18 V 12 = 0.25 02 .........= : 8 = 18 V R. = 15 0 e d 4 = 0.75 0 b) Write the Kirchhoff's 2nd rule (loop rule) for Loops abefa, abcdefa, bcdeb.Problem # 3 An aluminum wire has a length of 3.048 m and diameter of 2.588 mm. It is connected to 24 V power supply. The aluminum resistivity is 2.65>
