HAND CALCULATIONS
1. I=V/R I=0.00166A
0.00166*2000= 3.33V
0.00166*1000= 1.67V
3. 1/RT=1/R1+1/R2 = 1/2000+1/1000 = 1/0.0015, RT= 666.667 Ohms
V=I*R = 666.667*.003A = 2.00V
5. I1=0.6A
I2=0.3A
I3=0.3A
I4=0.15A
I5=0.15A
VR2=I2*R2 = 0.3*20 = 6.00V
I4*R4 = 0.15*20 = 3.00V VR4=
VR6=I5*R6 = 0.15*10 = 1.50V
