Experiment 2 - The Current in the Circuit

In order to understand exactly what is going on in the circuit in front of you, you have to measure the current directly in the circuit.

Measurement of the current I₁. (Enlarge)

Measurement of the current I₂. (Enlarge)

Measurement of the current I₃. (Enlarge)

Build it on the circuit shown. You measure the current I at three different points in the circuit.

At all three points you measure a current which is identical...

I₁ = I₂ = I₃

In an ideal situation you measure at all three points a current of...

I₁ = I₂ = I₃ = 45 mA

Circuit diagram measurement of the currents in the circuit.

Remarks

The measured values stated are ideal values. Your actually measured values certainly are different. The main reasons for this are...

Hence, always use the values you measured yourself when comparing the results.

In the next experiment, you look at the voltages in your circuit...
