Construct the network of Fig 122 and insert the measured val

Construct the network of Fig. 12.2 and insert the measured values of the sisters in the spaces provided. Caution: Be sure dc supplies are hooked up as shown (common ground) before turning the power on. Using mesh analysis, calculate the mesh currents I_1 and I_2 of the network. Use the measured resistor values and the indicated directions for the mesh currents. Then determine the current through each resistor and insert in Table 12.3 in the \"Calculated\" column. Include all your calculations and organize your work.

Solution

apply kvl to loop current i1

-20+1200i1+3300(i1-i2)+10=0

4500i1-3300i2=10

apply kvl to loop current i2

2200i2-10+3300(i2-i1)=0

-3300i1+5500i2=10

from the above equations

i1=6.349*10^-3 amps

i2=5.6277*10^-3 amps

current through 1200 ohms=i1=6.349*10^-3 amps

current through 2200 ohms=i2=5.6277*10^-3 amps

current through 3300 ohms=i1-i2=0.7213*10^-3 amps
