Circuit Analysis 7
Circuit Analysis Using KCL and KVL and 3 Simultaneous Linear Equations

Go to calculator

Can you spot the AI hallucination on the above drawing? KVL - Loop 2 , - I3I2 that is not a voltage drop.

Go to calculator

Using the calculator shown above, teachers and students can simulate different scenarios by changing the value of R1, R2, R3,R4,R5, V1,V2, and V3.

I1 + I2 + I3 = Eq. 1

Substitute the answer for I1, I2, I3 in equation 1, it should be very close to zero (0).
It means the answers are all correct.


I1 + I2 + I3 = Eq. 2

Substitute the answer for I1, I2, I3 in equation 2, it should be very close to
It means the answers are all correct.


I1 + I2 + I3 = Eq. 3

Substitute the answer for I1, I2, I3 in equation 2, it should be very close to
It means the answers are all correct.




INITIAL CONDITION:
Answer, I1 = -1.698 Answer, I2 = 5.774 Answer, I3 = 4.075

The negative current for I1 means, the actual current is flowing in opposite direction of the assumed current direction.


PRACTICE SIMULATION: if you are troubleshooting the same circuit. Then you can update new values and check the expected values. if your actual test reading does not match the expected values then one of the components is defective.

R1 = 5 R2 = 10 R3 = 10 R4 = 4 R5 = 30
V1 = 30 V2 = 120 V3 = 60

Update any values of R1, R2, R3, V1, and V2 for troubleshooting. The equation will be updated for new data entry.
