Kirchhoff's laws with Cobra SMARTsense

Principle
In the experiment, a circuit is set up in which various resistors are connected in such a way that both the node rule and the mesh rule can be worked out independently. To do this, the voltage at the individual components and the currents at the node are measured and added or subtracted.

Tasks

1. The currents running in and out of the nodes are to be measured.
2. Tthe voltages at the individual resistors should be measured.
3. Derive Kirchhoff's rules.

Learning objectives
The aim of the experiment is to learn how currents and voltages are distributed in an electrical circuit.

Advantages

• Simple setup in just a few minutes.
• High resolution data acquisition (up to 10 kHz).
• Improved media competence.
• Safe student power supply (RiSU-compliant).
