Question

2- Set the two independent power sources to Vsi 6V and Veo" 10 V and measure their actual values using the DMM. Actual Values of power sources: 4.47 VS15.99 Vs- 3- Using the breadboard construct the circuit shown in Figure 4,1 (repeated below for convenience). Use the resistors measured in Step 1 (above) and the power sources Vsi- 6 V, and Vs2 -10 V. IR3 IRI RS.

Record your results in Table 4.3. Indicate always the units. Table 4.3- Measured Mesh Currents is is Mesh currents: 238m4 (measured) 33 MA 30m4 50

Answer 1

Apply KVL in loop (1) we get 1500i_1, + 1000 (i_1 i_2) = 6 2500i_1, - 1000i_2 = 6 rightarrow (1) Applying KVL in loop (2) we get 3300i_2 + 5600 (i_2 -i_3) + 1000 (i_2 - i_1) = 0. - 100i_1 + 9900i_2 - 5600i_3 = 0 rightarrow (2) Applying KVL in loop (3) we get 2000i_3 + 5600 (i_3 - i_2) = -10. - 5600i_2 + 7600i_3 = -10 rightarrow (3) Solving equation (1), (2) and (3) we get. I_1 = 2.03 times 10^-3 A = 2.03 mA i_2 = -9.24584 times 10^-4 A = -924.584 mu A i_3 = -1.99 times 10^-3 A = -1.99 m A From Multisim result we get i_1 = 2.03mA i_2 = -924.584uA i_3 = -1.997mA

2.MULTISIM RESULT

From MultiSim result we get

i₁=2.03mA

i₂= - 924.584uA

i₃= - 1.997mA
