Question

Use these equations to get the calculated currents for R1-R3 based off the data in the table:

I1 + I2= I3

E3 - I1R1 -I3R3 = 0

E2 - I2R2 - I3R3 =0

  -10.41 V

-11.52 A (120/10.41)

0.09 A

 

 

 

 7.59 V

10.54 A (80/7.59)

0.09 A

 

 

 

0.41 V

121.9 A (50/0.41)

0.008 A

 

 

** Currents in column 2 and 4 should be very close
