Experiment 6 - Kirchhoff's Current Law (KCL) II

You can easily check the Kirchhoff's Current Law. In order to do this you measure the currents in the circuit.

Build the circuit as shown.

Measurement of the current I₁. (Enlarge)

Measurement of the current I₂. (Enlarge)

Measurement of the current I₃. (Enlarge)

The three measurements are (ideal values)...

I₁ = 82.5 mA

I₂ = 7.5 mA

I₁ = 75.0 mA

With that you can easily verify the KCL...

I₁ = I₂ + I₃

What can be said about voltages in a branched circuit...?
