This circuit is designed to verify Kirchhoff’s Current Law (KCL), which states that:
The total current entering a junction is equal to the total current leaving the junction.
In this circuit, a 1 V DC voltage source is connected to two resistors in parallel:
R1 = 10kΩ
R2 = 4.7kΩ
The current from the source (𝐼𝑆) splits at the junction into two branches:
I1 = 100μA, flows through R1
I2 = 213μA, flows through R2
According to KCL:
I𝑆 = I1 + I2
Substituting the values:
313 μA ≈ 100μA + 213μA
