Kirchhoff’s Laws: Kirchhoff’s Current Law with Cobra SMARTsense

Principle

In this experiment, an electrical circuit is set up in which various resistors are connected in such a way that Kirchhoff’s Current Law can be derived independently. To achieve this, the currents at a node are measured and added or subtracted accordingly.

Tasks

1. Build an electrical circuit with resistors and nodes.
2. Determine the current before and after a node.
3. Determine the voltage across a resistor and calculate the current.
4. Derive Kirchhoff’s Current Law.

Learning objective

The aim of this experiment is to understand how currents are distributed within an electrical circuit.

Benefits

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