5.2 Heating effect of electric currents

Experiments

Here are experiments our science specialists have selected to support the IB* topic.

Ohm's Law

Experiment #22 from Physics with Vernier

  • Determine the mathematical relationship between current, potential difference, and resistance in a simple circuit.
  • Compare the potential vs. current behavior of a resistor to that of a light bulb.

Series and Parallel Circuits

Experiment #23 from Physics with Vernier

  • To study current flow in series and parallel circuits.
  • To study potential differences in series and parallel circuits.
  • Use Ohm’s law to calculate equivalent resistance of series and parallel circuits.

Heat as Energy Transfer

Experiment #34 from Physics Explorations and Projects

  • Design and perform an investigation.
  • Draw a conclusion from evidence.
  • Explore how to account for thermal energy transfer during energy transformation events.
