Voltaje:
VR1 = R1 · IR1 = 229 · 0.00349 = 0.799 V
VR2 = R2 · IR2 = 1493 · 0.00245 = 3.65 V

VR3 = R3 · IR3 = 2690 · 0.00143 = 3.84 V
VR4 = R4 · IR4 = 220 · 0.00041 = 0.0902 V
VR5 = R5 · IR5 = 812 · 0.00012 = 0.0974 V
VR6 = R6 · IR6 = 180 · 0.0005 = 0.09 V
VR7 = R7 · IR7 = 3910 · 0.00106 = 4.14 V
VRef = Ref · IRef = 87.1 · 0.00106 = 0.0928 V
VRcd = Rcd · IRcd = 790 · 0.00429 = 3.39 V
Potencias:
PR1 = VR1 · IR1 = 0.801 · 0.00349 = 0.00279 W
PR2 = VR2 · IR2 = 3.39 · 0.00245 = 0.0083 W
PR3 = VR3 · IR3 = 3.39 · 0.00143 = 0.00484 W
PR4 = VR4 · IR4 = 0.0928 · 0.00041 = 0.000038 W
PR5 = VR5 · IR5 = 0.0928 · 0.00012 = 0.000011 W
PR6 = VR6 · IR6 = 0.0928 · 0.0005 = 0.000046 W
PR7 = VR7 · IR7 = 4.1 · 0.00106 = 0.00434 W
PRef = VRef · IRef = 0.0928 · 0.00106 = 0.000098 W
PRcd = VRcd · IRcd = 3.39 · 0.00429 = 0.0145 W
PRab / Total = VRt · IRt = 4.19 · 0.00453 = 0.0189 W
