how do you work these problems for r1 shorts,r1 opens,r2 shorts, and r2 opens
R1 14= 5.1 mA It= 5.1 mA V1 = 5.1 V 1 kohm 11= 5.1 mA P4= 26 mw P1= 26 mw V2= 1.8 V 12= 3.6 mA R2 500ohm R3 Vs 12V 1.2kohm V3= 1.8 V P2= 6.48 mW 13= 1.5 mA R4 Pt= 61.2 mW V4= 5.1 V P3= 2.7 mW 1 kohm D In the circuit above, R1 shorts. Find V1= OV V2= 3.13 V V3= 3.13 V V4= 8.87 V 14= 8.87 mA 11= 8.87 mA 12= 6.26 mA 13= 2.61 mA V2= OV 0 In the circuit above, R1 opens. Find V1= 12 V V3= OV V4= OV 11= O A 12=0 A 13= 0 A 14= OA V2=0V V3= 0 V V4= 6 V In the circuit above, R2 shorts. Find V1= 6 V 11= 6 mA 12= 6 mA 13= 0 A 14= 6 mA V2= 4.5 V V3= 4.5 V V4= 3.75 V In the circuit above, R2 opens. Find V1= 3.75 V 11= 3.75 mA 12=0 A 13= 3.75 mA 14= 3.75 mA
